Asked if she had romanced her co-star on the set of the new sequel, model-turned-actress Huntington-Whiteley jokes, "It was tough. I really had to tie myself into my trailer. I really had to restrain myself.

"Seven months of shooting, it was really tough for me. I had to wear a chastity belt and everything."

Huntington-Whiteley's real-life boyfriend is British action man Jason Statham.
