"I am sad to inform my fans that after seven years, Paul and I have decided to amicably end our marriage," Patrick wrote in a statement. "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."
Hospenthal, a physical therapist, was not often present by Patrick's side during pre-race events in the way that many other NASCAR spouses are. The two met while he was treating Patrick for a non-racing injury, and married in 2005.
This year, Patrick was named the most popular driver in NASCAR's Nationwide series, and will begin racing full time in the top-level Sprint Cup series next year for Tony Stewart's Stewart-Haas Racing.
