Kelly Brook and fiancé Billy Zane didn't have sex with one another until they had finished shooting new movie Three together. The couple fell for each other on the set of the movie, but kept a lid on their romantic feelings until the film wrapped.

Kelly told Daily Star newspaper: "On set, I was initially just too concerned about the work, I was too wrapped up in the insecurity of trying to be professional. I just started going to Billy for advice and help. It was a professional relationship. Because he was so talented, I got to know that side of him first."

She added: "Any romance or hanky panky had to wait until after the movie. It's very much like athletes - you save it for after."

Meanwhile, the lovebirds are planning to tie the knot on a Greek island. The 26-year-old revealed: "Billy is 100 per cent Greek, so we're thinking of holding the wedding there.

"Greece is so lovely. We haven't set a date yet but when we do we'll let everyone know."
