London, Apr 18 (ANI): Pixie Lott has finally revealed the secret behind her fabulous figure.

The singer has attributed her chiselled body to having lots of sex with her man Oliver Cheshire.

I love eating a proper meal and there is no way I could go on a diet or watch what I eat, the Daily Star quoted Cheshire as saying.

To keep in shape I have lots of sex. I call it sexercise, he said.

According to him, he doesn't get any complaints from Pixie, 21, about what he's packing downstairs.

Chatting about his recent swimwear shoot for M and S he said: I wasn't nervous about posing in swimwear as I've been in my pants since I was 15 and was born naked.

Plus, I don't need to stuff, he added. (ANI)
