Danica Patrick files for divorce

CHARLOTTE, N.C. -- Sprint Cup Series driver Danica Patrick has cited an "irretrievably broken" marriage as the cause for her filing for divorce with Paul Hospenthal.

Patrick filed for divorce on Jan. 3 in the Superior Court of Arizona in Maricopa County, according to documents obtained by ESPN.com on Monday.

The 30-year-old driver announced on Facebook the decision to divorce on Nov. 20, the day after she was named the most popular driver in the Nationwide Series.

"My marriage is irretrievably broken and there is no reasonable prospect of reconciliation," Patrick said in the filing that she signed on Dec. 31.

According to the documents, Patrick and Hospenthal entered into a prenuptial agreement prior to their marriage in 2005 that defined property interest. She stated no alimony will be necessary.

"My spouse and I did acquire community property during our marriage, and it will be divided as indicated on a Settlement Agreement which will be submitted to the court at a later date," Patrick said in the filing.

The documents cited there have been no incidents of domestic violence and there are no children.

Hospenthal, 17 years older than Patrick, is a physical therapist in the Scottsdale, Ariz., area. The divorce cannot be finalized until at least 60 days after he has been served the papers. He has a right to respond to Patrick's filing.

Patrick finished 10th in the Nationwide Series this past season for JR Motorsports. She is moving full time to the Cup series this season for Stewart-Haas Racing.

The former IndyCar star consistently has avoided discussing her private life over the years. Media members were informed she would adhere to that policy during last week's Cup test at Daytona International Speedway.

Her only public mention of the divorce came on Facebook.

"I am sad to inform my fans that after 7 years, Paul and I have decided to amicably end our marriage," she wrote. "This isn't easy for either of us, but mutually it has come to this. He has been an important person and friend in my life and that's how we will remain moving forward."
