Rosie Huntington-Whiteley joked she had to wear a chastity belt to resist Shia LeBeouf.

The British beauty replaced Megan Fox as the female lead in the third instalment of the 'Transformers' sci-fi action franchise, and following revelations Shia had a brief fling with Megan when they were filming, Rosie joked she had trouble resisting him too.

Speaking on TV show 'Chelsea Lately' the former underwear model said: "It was tough. I really had to tie myself into my trailer! I really had to restrain myself. It was really tough for me. I had to wear a chastity belt!"

Rosie, 24, is actually dating fellow action film star Jason Statham, who celebrated her winning the role in 'Transformers: Dark of the Moon' with a practical, but rather unorthodox present.

Rosie explained: "I came back from filming after about two weeks covered in bruises, like head to toe and he was like, 'Babe, you got to wear your stunt pads!'

"He's very sweet. He sent me these like razor thin gel stunt pads that stuntmen wear on the movies that he does."
