Jake Gyllenhaal had a major crush on former co-star Jennifer Aniston. Both of them acted in The Good Girl in 2002.
He revealed this during an interview with People's Jess Cagle, "She's a rough one, you know, not likable. So hard to compliment. I will say, I had a crush on her for years. And working with her was not easy...I was–um, yeah. That's all I'm going to say. It was lovely. It wasn't hard, that's what I would say."
