She is part of the Rooney family behind the Pittsburgh Steelers, shares a son with actor Kevin Costner, and later married billionaire businessman William “Bill” Koch. These connections have made people curious about Bridget, even though she has generally chosen a much more private life than the celebrities around her.

Who Is Bridget Rooney?
Bridget Rooney is an American woman from one of the best-known families in professional football.
The Rooney name is strongly connected with the Pittsburgh Steelers. Her grandfather, Art Rooney, founded the football team in 1933. The Rooney family continued to be closely involved with the franchise for generations.
However, football is only one reason people search for Bridget.
She also became known because of her relationship with Hollywood actor Kevin Costner during the 1990s. The pair had a son together, Liam Costner.
Years later, Bridget married businessman and billionaire William Koch, often called Bill Koch.
These relationships placed Bridget at the meeting point of three powerful worlds: professional sports, Hollywood and American business.
Still, Bridget has never appeared to chase celebrity status in the way many public figures do.
Bridget Rooney Comes From the Famous Rooney Family
Understanding Bridget Rooney’s story begins with her family.
Her grandfather was Arthur Joseph “Art” Rooney, the man who founded the Pittsburgh Steelers.
Christie’s described Bridget Rooney Koch as being born into the Rooney family and specifically identified Art Rooney as her grandfather. The auction house also noted that the family has continued its stewardship of the Steelers organization.
That is a major part of Bridget’s background.
For many Americans, the Rooney name is almost impossible to separate from football.
The Steelers have developed into one of the NFL’s most recognizable franchises, making the family’s history important far beyond Pittsburgh.
Bridget therefore grew up connected to a family with a long sporting legacy.
However, she built a life that was mostly separate from professional football itself.
Is Bridget Rooney Related to Art Rooney?
Yes.
Bridget Rooney is Art Rooney’s granddaughter.
This detail is supported by multiple sources, including Christie’s and published biographical information about Bill Koch.
Art Rooney founded the Pittsburgh Steelers and became one of the important names in the development of professional football in America.
For Bridget, this means the Steelers connection is not simply a distant association.
It is part of her direct family history.
Bridget Rooney and Kevin Costner’s Relationship
One of the biggest reasons Bridget Rooney became known outside sporting and social circles was her relationship with Kevin Costner.
Costner was already a major Hollywood star by the 1990s.
He had appeared in hugely successful movies and had become especially famous for films such as Dances with Wolves, Field of Dreams and The Bodyguard.
After his first marriage ended, Costner had a relationship with Bridget Rooney.
The relationship did not lead to marriage, but the couple welcomed a son together in 1996.
Kevin Costner’s biographical record confirms that he had a brief relationship with Bridget Rooney and that the two had a son.
Their relationship continues to attract attention because both people came from very different but highly visible worlds.
Costner represented Hollywood fame.
Bridget represented a powerful American sports family.
Did Bridget Rooney Marry Kevin Costner?
No.
Bridget Rooney and Kevin Costner were romantically involved, but they were never married.
Their relationship took place after Costner’s first marriage to Cindy Silva had ended.
Although their romance did not last, it became an important part of both of their personal histories because they share a child.
Their son is Liam Costner.
Bridget Rooney and Kevin Costner’s Son Liam
Bridget Rooney and Kevin Costner welcomed their son, Liam Costner, in 1996.
People magazine includes Liam among Kevin Costner’s seven children and identifies Bridget Rooney as his mother.
Liam has generally stayed far more private than his famous father.
That makes him different from many celebrity children who grow up heavily covered by entertainment media.
Kevin Costner has children from more than one relationship, and Liam is part of his large blended family.
Bridget, meanwhile, appears to have kept much of her son’s upbringing outside the constant Hollywood spotlight.
Why Is Liam Costner Famous?
Liam Costner mainly became publicly known because of his parents.
His father is Kevin Costner, one of Hollywood’s most recognizable actors and filmmakers.
His mother, Bridget Rooney, belongs to the family connected with the Pittsburgh Steelers.
That gives Liam connections to both Hollywood and one of America’s most famous sports families.
Yet he has not built his public identity around acting or celebrity appearances.
This quieter approach appears similar to Bridget’s own relationship with fame.
What Happened Between Bridget Rooney and Kevin Costner?
Their romantic relationship eventually ended.
There is no need to turn that simple fact into a dramatic story.
Many celebrity-focused websites have published different versions of their breakup over the years, but reliable mainstream sources clearly establish the important facts: Bridget and Costner had a relationship, they had Liam together, and they later went on to separate lives.
Costner later had other relationships and eventually remarried.
Bridget also moved forward with her life and later married businessman Bill Koch.
Who Is Bridget Rooney’s Husband?
Bridget Rooney’s husband is William Ingraham Koch, better known as Bill Koch.
Bill Koch is an American businessman who founded Oxbow Carbon.
He is also known for his interest in art, historical items and collecting.
Outside the business world, Koch gained attention in sailing when his yacht America³ won the America’s Cup in 1992.
Bridget and Bill Koch married in 2005 in Colorado.
The marriage created another interesting family connection.
Bridget was already part of the Rooney sports dynasty and had a child with one of America’s most famous actors.
Her marriage then linked her to another major American business family.
Bridget Rooney and Bill Koch’s Marriage
Bridget and Bill Koch have been married for more than two decades.
Unlike many celebrity couples, they have not built their marriage around reality television, social media posts or constant interviews.
They do occasionally appear together at important events.
They have also been associated with charity and civic activities.
In 2008, for example, Bridget Rooney Koch and William Koch received a Palm Tree Award from the Palm Beach Police Foundation in recognition of civic activity and philanthropy.
This gives another side to Bridget’s public image.
Much of the internet focuses on her famous relationships, but she has also been connected with charitable and community events.
Does Bridget Rooney Have Children with Bill Koch?
Yes.
Bridget Rooney and Bill Koch have a daughter named Kaitlin.
Published information about Bill Koch confirms that Bridget and Bill have one daughter together.
That means Bridget is the mother of at least two publicly documented children:
Liam Costner, whom she shares with Kevin Costner, and Kaitlin Koch, whom she shares with Bill Koch.
Bridget’s family life has remained relatively private despite the famous names surrounding it.
Bridget Rooney’s Life as Bridget Rooney Koch
After marrying Bill Koch, Bridget became widely known as Bridget Rooney Koch.
That name now appears in social coverage, charity events, property reporting and even the art and jewelry world.
In 2026, Christie’s featured jewels from the collection of Bridget Rooney Koch as part of its Magnificent Jewels sale.
The auction house described her as a passionate collector who had assembled notable gems and jewelry over time.
This is an interesting detail because it shows Bridget has interests beyond simply being connected to famous men or families.
Her collection included important pieces featuring precious stones such as spinels and rubies.
Bridget Rooney’s Interest in Collecting
Collectors often spend years learning about quality, history and design.
Christie’s described Bridget’s collection as something built over a considerable period.
The auction house highlighted her interest in high-quality gems and fine jewelry.
It offers a rare look at one of Bridget’s personal interests.
Because she does not regularly give celebrity interviews, information about her individual tastes can be difficult to find.
Her jewelry collection therefore tells readers something about the person behind the well-known family name.
Bridget Rooney and Philanthropy
Bridget Rooney Koch has also appeared at charitable and civic events with her husband.
Their involvement with the Palm Beach Police Foundation is one documented example.
The pair served as honorary chairmen at a fundraising event and received recognition for civic activity and philanthropy.
Bridget and her husband have also appeared in donor records connected with major cultural institutions.
A Smithsonian campaign publication, for example, listed Bridget Rooney and William I. Koch among donors of $25,000 or more.
This part of her story receives less attention online than her Kevin Costner connection.
Still, it helps provide a more complete picture of her public life.
Does Bridget Rooney Live a Private Life?
For someone connected to so many famous people, Bridget Rooney keeps a surprisingly low profile.
She does not maintain the same kind of public celebrity presence as an actor, singer or television personality.
Much of what becomes publicly known about her comes from events she attends with her husband, property stories or coverage connected with her family.
That appears to be a deliberate way of living.
She can move within famous social circles without turning every part of her personal life into entertainment news.
Bridget Rooney and Bill Koch’s Aspen Property
Bridget and Bill Koch have owned major properties over the years, including an estate near Aspen, Colorado.
The couple’s Elk Mountain Lodge estate attracted widespread attention when it was offered for sale.
The Wall Street Journal reported that the couple decided to sell as they became empty-nesters.
The property was eventually sold in 2026 after years of appearing on and off the market.
Reporting said the Aspen estate fetched about $33.5 million at auction.
This recent development offers a small glimpse into Bridget and Bill’s current stage of life.
With their children grown, they appear to be simplifying at least part of their property portfolio.
Where Is Bridget Rooney Now?
Bridget Rooney continues to be known publicly as Bridget Rooney Koch.
Recent reporting still identifies her as Bill Koch’s wife.
In 2026, coverage surrounding their Aspen property described the couple as empty-nesters who were downsizing.
She has also remained connected to the collecting world through the sale of pieces from her jewelry collection.
There is little evidence that Bridget wants to become a traditional celebrity.
Instead, her life continues largely through family, social, collecting and philanthropic circles.
How Old Is Bridget Rooney?
Reliable published sources list Bridget Rooney as being born in 1962.
That would make her around 63 or 64 years old in 2026, depending on her exact birthday.
Some entertainment websites publish a specific date of birth, but not all of those details are supported by equally strong sources.
For accuracy, it is safer to use the well-supported birth year rather than present an uncertain date as fact.
What Is Bridget Rooney’s Net Worth?
There is no reliable, independently confirmed public figure for Bridget Rooney’s personal net worth.
This is important because many celebrity websites publish large numbers without showing how they calculated them.
Bridget comes from the wealthy Rooney family and is married to billionaire businessman Bill Koch.
However, a husband’s estimated fortune should not automatically be presented as his wife’s personal net worth.
For that reason, any exact figure claiming to represent Bridget Rooney’s individual wealth should be treated carefully unless supported by reliable financial records.
Is Bridget Rooney an Actress?
Some online biographies describe Bridget Rooney as an actress or mention a small acting credit.
However, acting is not what she is mainly known for, and reliable mainstream coverage focuses much more on her Rooney family background, Kevin Costner connection, marriage to Bill Koch and social activities.
Calling her a major actress would therefore give readers the wrong impression.
Her public recognition comes primarily from her family and personal connections.
Why Does Bridget Rooney Continue to Interest Readers?
Bridget Rooney’s story is unusual because it crosses several areas of American culture.
She comes from a football dynasty.
She had a relationship and child with a major Hollywood star.
She later married a billionaire businessman.
She has attended major social and charitable events.
And yet she has remained relatively private throughout all of it.
That contrast naturally creates curiosity.
Readers often know the names around Bridget before they know much about Bridget herself.
