Katherine McPhee, who was the runner-up to Taylor Hicks on the "American Idol" reality show, is now engaged to actor Nick Cokas, according to PEOPLE, citing an unnamed source.

The news evidently broke when McPhee couldn't help showing off her ring from Cokas. The two, who met while performing "The Ghost and Mrs. Muir" at the Los Angeles theater, have been seeing each other for over a year.

McPhee added that things began to really take off for the two when "He took me up to my San Francisco (Idol) audition. We totally fell in love" at that time.

According to the source, "Katharine is bubbling over with excitement for her upcoming wedding. She is all smiles when she talks about the planning. It sounds like everything is going very smoothly."
