Aniston felt tiny next to tall Vaughn

Jennifer Aniston spent weeks nursing sore feet as she filmed The Break-Up with boyfriend Vince Vaughn last year - because the actress was forced to wear high heels to match up to the tall actor.

The 5-foot-5 actress was a whole foot shorter than The Wedding Crashers funnyman and found wearing stilettos everyday took their toll on her feet.

Aniston tells Harper's Bazaar magazine: "We had a ball making the movie, though with him at 6-foot-5 and me at 5-foot-5, they had trouble keeping us in the same frame.

"I was constantly having to wear these incredibly high heels, which was like having a workout.

"With certain people you just feel instant friendship. And as an actor, Vince is one of the funniest people I've ever met."
