Katharine McPhee was on set of her new movie ‘House Bunnies’ in which she plays a pregnant hippie student. She opened up about wearing a fake pregnant belly and how she’s not ready for kids just yet.

“Today is the first day I’m wearing the prosthetic belly, which wraps all the way around [to] my back, and it’s actually really comfortable,” Kat revealed to Entertainment Tonight. “I’m really enjoying it. It’s hot and sweaty though, but it’s like Method acting.”
