The 34-year-old actress’ former Grey’s Anatomy co-star Ellen Pompeo recently opened up about Katherine‘s exit on the show.
“When Katie left, it was tough,” Ellen expressed to the New York Post. “You could understand why she wanted to go — when you’re offered $12 million a movie and you’re only 26. But Katie’s problem is that she should not have renewed her contract. She re-upped, took a big raise and then tried to get off the show. And then her movie career did not take off.”
