Rosie Huntington-Whiteley Had To "Restrain" Herself From Hooking Up With Shia LaBeouf

Move over, Megan Fox!

Shia LaBeouf recently confessed to a steamy on-set hookup with former Transformers co-star Fox. So, on Chelsea Handler's late-night show, current co-star Rosie Huntington-Whiteley joked that she had a hard time keeping her hands off Shia LaBeouf on the set of Transformer: Dark of the Moon.

The Victoria's Secret Angel "confessed" on Chelsea Lately, Thursday night:

"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!"

Chelsea agreed, quipping that it must be hard for Rosie to keep her hands off of short co-stars.

Whiteley has been dating sexy British actor Jason Statham for more than a year, and while she's significantly taller than her man when she wears high heels, the Transformers star tells Handler "he loves it."
