Keira Knightley's ex-boyfriend has spilled the beans about their relationship.

23-year-old Jamie Dornan told The Sun: "There is a big pressure when you go out with someone such as Keira. The man is meant to be the alpha in the relationship on the money and the power front and clearly I was not.

"You feel like you have to be dominant in other areas and that causes problems. Keira could see what I was going through. She was the one who finally said: 'OK, that's it, I've had enough'."

Knightley is now dating Pride & Prejudice co-star Rupert Friend.
