Katharine McPhee to Guest Star on Ugly Betty

Katharine McPhee is kicking off sweeps month on Ugly Betty. Last season's American Idol runner-up will appear as herself on the Feb. 1 episode, "I'm Coming Out," about Mode's runway show.

The show will air two days after McPhee's self-titled album hits stores. Ugly Betty stars newcomer, America Ferrera.

This is the second annoucement in a week of an American Idol alum jumping onto the small screen. Kelly Clarkson will guest star on an upcoming episode of Reba, as well.
