Keira Knightley says she is an emotional wreck

British beauty Keira Knightley has revealed that she often wonders how her boyfriend Rupert Friend puts up with her, because she is so emotionally unstable.

The Oscar-nominated actress is currently dating her Pride and Prejudice co-star Rupert Friend, and admits she pushes him to the limit.

"I'm awful. I always have freak-outs. I don't know why anyone puts up with me. I'm mostly an emotional wreck! It's stupid s**t. I don't freak out about anything that actually warrants a freak-out,” she was quoted by Contactmusic, as saying.

Knightley claims even the smallest problem send her on a downward spiral.

“It's the little stuff I can't deal with. Anyone who has gone out with me will tell you I have this awful tendency to cry when I get really angry. And I can't stop. If I could stop it I would, because I can occasionally come up with some fantastically cutting one-liners in fights.

"I'll come out with one and say, 'Oh, that was great.' But suddenly I'll find I'm crying. And I'll be like, 'S**t, I completely ruined my one-liner.' It's annoying!" she added. (Asian News International photosource:justjared.com)
