Ain't No Mountains Heigl-nough: As the voluptuous Dr. Izzie Stevens, she represented the only silver lining for guys who get stuck watching Grey’s Anatomy with their ladies. Thankfully, director Judd Apatow took Katherine out of her shapeless scrubs for her role in Knocked Up. She's currently starring in the upcoming rom-com The Ugly Truth, which guarantees you at least 100 minutes of naptime this week.
