A judge has ordered Dallas Cowboys owner Jerry Jones to take a paternity test to prove he is the biological father of a fully grown woman.

According to the Dallas Morning News, Alexandra Davis, 26, filed a paternity lawsuit in March against Jones. Davis claims her mother and Jones had a relationship in the mid-1990s.

Jones met Davis’ mother when she was a ticket agent at Little Rock, Arkansas Airport. They began a relationship while she was estranged from her first husband. DNA testing during her mother’s divorce showed that Davis was not the biological daughter of her mother’s husband, the lawsuit said.

Lawyers representing Jones argued that Davis’ lawsuit is one of many attempts to extort Jones and the Dallas Cowboys over the years. Jones reportedly paid Davis’ mother monthly support until the girl was 18. She never legally proved paternity.

Davis has received about $3.2 million via her mother’s agreement with Jones, including four years of paid tuition at Southern Methodist University, trips around the world and about $70,000 for a Range Rover, according to court documents.

A lawyer who helped arrange the payments on behalf of Jones to Davis and her mother claims Davis has demanded an additional $20 million.

Although her lawsuit has been described as a “money grab,” Davis and her attorney claim she doesn’t want his money.

“We’re not asking anything,” Bergman said Friday, according to the Dallas Morning News. “It’s just a legal right to have a parent. I think this has been a very emboldening endeavor for her… The irony is I think Jerry Jones would be really proud of her if he really knew her.”

Bergman filed a motion to compel Jones to submit to a paternity test in October, and a hearing took place on the motion on Tuesday.

According to the Morning News, a judge issued the ruling on Thursday, ordering the 80-year-old multi-billionaire to take a paternity test.

Jones’ lawyers argued that since Davis was born during her mother’s first marriage, it was presumed that her first husband was the father.
