"American Idol" runner-up Clay Aiken will be a guest judge on tonight's episode of "America's Next Top Model," which airs 8 p.m. on the CW.
Aiken will reportedly serve as an acting coach to the eight remaining finalists. He had a stint appearing in "Monty Python's Spamalot" on Broadway.
Aiken recently made headlines for helping his friend, Jaymes Foster, conceive a son through in-vitro fertilization. He placed second in Season 2 of "Idol" -- right behind champ Ruben Studdard.
