SCARLETT JOHANSSON has revealed the secret behind her "nice body, taut legs and great butt" - she stays in shape playing tennis.

The actress fell in love with the sport while shooting new WOODY ALLEN movie MATCH POINT and claims it has turned her body to steel.

She says, "Every day I had to practise on the tennis court - and I'd never held a racket before. Tennis is great. You don't even notice how much you run. You get a nice body, taut legs and great butt. I'll keep on playing if I find a good partner. But I want to win every time. I am very ambitious."
