Hey Crunchers, are we buying Katharine McPhee as an actress, or should ole girl stick simply to singing?

The American Idol 5 runner-up, who cut her teeth on last fall’s sorority-themed comedy The House Bunny, was spied on the set of her latest movie, You May Not Kiss The Bride, which is filming in Hawaii this week.

K.P. is co-starring with Dave Annable in the romantic-comedy about an arranged marriage between a mobster’s daughter and a photographer.

Sounds promising….
