Keira Knightley Regrets Giving Up Ballet.

The Pirates Of The Caribbean beauty admits her dedication to acting from an early age meant she had to sacrifice other childhood pursuits - namely, her beloved ballet.

She says, "I adore the ballet, especially Swan Lake. I try to see as many ballets as I can but it's not something I've thought of doing myself."

"You have to start at it very young so I missed out and acting was always my thing."
