Actor MATTHEW FOX shocked his co-stars in American TV drama Lost by encouraging everyone to strip off for a skinny-dipping bonanza while filming in Hawaii.

The cheeky heart-throb was determined to make the most of the good-looking actresses in his presence, but he also insists the eye-popping idea was essential for cast "bonding".

He says, "It may sound crazy, but there is a bit of a strategy behind that. We have some very beautiful girls in the cast.

"But it's also a good bonding experience. I felt that late-night partying and getting people to take their clothes off was a good thing.

"We've had some dissenters - some people not wanting to join Foxy's Skinny-Dipping Crew. But I'll get them all."
