"My marriage is irretrievably broken and there is no reasonable prospect of reconciliation," the 30-year-old wrote in the divorce documents filed in Arizona on Jan. 3.
Patrick first announced her plans to divorce Hospenthal, a physical therapist, on Facebook in November 2012.
"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."
