American Idol runner-up Katharine McPhee is giving acting a shot. She has been cast as a sorority girl in an upcoming Adam Sandler-produced movie that does not yet have a title.

According to Entertainment Weekly, McPhee will "co-star" alongside funny girl Anna Faris, who plays a Playboy bunny who has been evicted from the mansion. Faris becomes a den mother to a super lame sorority, of which McPhee is a member. Rumer Willis also has a role. It will reportedly begin shooting late this summer.

Katharine has a background in acting-- according to her official bio, she studied at the Boston Conservatory and the California State Summer School for the Arts. She even had a role in an MTV pilot that never made air. What I'm trying to say is... the girl has been groomed for this kind of thing.
