Kelly's big fat Greek wedding

Kelly Brook and Billy Zane revealed plans for their big fat Greek wedding ahead of the national opening of their new movie

British sex bomb Brook and Titanic star Zane fell in love on the set of the movie, a steamy thriller called Three, and are now planning to wed on a Greek island.

Three opens nationwide on May 5.

The lovebirds were in London's Leicester Square for the movie's premiere yesterday.

"My roots are Greek and also they know how to throw a good party. They do it right," said Zane, 40.

"I don't know whether we'll do a traditional wedding or a hybrid. We'll probably create our own thing.

"But it will be a big fat Greek hoedown."

Brook, 26, added: "We haven't set a date yet but when we do we'll let everyone know."

The former Big Breakfast presenter and host of Celebrity Love Island was recently voted the star with the body most women want.

She showed off her curves on the red carpet in a tight-fitting teal coloured dress.

Zane told reporters: "She has the body that all the guys want too. I feel like the luckiest man alive."

In the film, Zane and Brook play a wealthy businessman and his young wife who are shipwrecked on a desert island with a deckhand - leading to a deadly love triangle.

Asked whether she fell for Zane of the first day of filming, Brook replied: "Probably deep down in my belly I did, but there was so much else to think about because I was concentrating on work.

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

The former model recently launched her own range of 1950s-style swimwear.

She said her screen idols were Sophia Loren and Marilyn Monroe, explaining: "Everything was so glamorous then. I'm just in love with that whole period."
