U.S. racing car driver and model Danica Patrick has filed for divorce from her husband of seven years.

She filed legal papers to end her marriage to physical therapist Paul Hospenthal on 3 January (13), stating she wouldn't be seeking spousal support and adding the couple had a prenuptial agreement.

The documents read: "My marriage is irretrievably broken and there is no reasonable prospect of reconciliation."

Patrick first announced news of their separation in November (12), writing in post on Facebook.com, "I am sad to inform my fans that after 7 years, Paul and I have decided to amicably end our marriage. 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."
