Patrick moved to the Philadelphia area earlier this year after being contacted by a West Chester woman named Donna McCall, a former Philadelphia Eagles cheerleader who had a crush on Patrick from her childhood.

"I met him for the first time," McCall told the Johnstown Tribune-Democrat, "but I feel like I've known him forever."
McCall announced last week that they had split.
