Former American Idol contestant Katharine McPhee tied the knot on Saturday in Los Angeles! The 23-year-old singer/actress married producer Nick Cokas, People reports. Among the 305 guests were fellow American Idol season five contestants Kellie Pickler and Mandisa. "[Nick] is the love of my life," Katharine says. "This is a once in a lifetime occasion and everything is just perfect."

Katharine and Nick met and became friends in 2005 and started dating when she auditioned for American Idol; Nick was her rock as she struggled with the show's pressures, her secret eating disorder, and her most recent crisis of being dropped by her label.

The only creepy thing? Nick is 42. He could technically be her dad! Ewww!
