Patrick announced the split with Paul Hospenthal on her Facebook page Tuesday.
"I am sad to inform my fans that after seven years, Paul and I have decided amicably end our marriage," she said. "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 is a physical therapist who met Patrick while treating her for a non-racing injury. The two were married in 2005, and he is 17 years older than the 30-year-old driver. (FOX News)
