Katherine Heigl is best known for her role as Izzy Stevens on Grey’s Anatomy, but the 30 year old did work before that. She starred in Roswell, Valentine, and the classic Segal flick Under Seige 2: Dark Territory. She has become a bit spoiled and the writers of Grey’s are contemplating killing her off with a brain tumor. Not that big of a deal though sine she is becoming a consistent box office draw with Knocked Up, 27 Dresses, and her soon to be release The Ugly Truth will also do well. I just wish she would up the sexuality a bit because she doesn’t get as sexy as these picture much anymore.
