Crew on new film St. Trinian's were given a shock by cross-dressing actor Rupert Everett when his fake breasts exploded all over the set.

The flamboyant Everett and co-star Colin Firth were constantly playing pranks on the set of the British movie remake, and one involved replacing his hefty prosthetic cleavage with water bombs.

Everett explains, "For the love scene, I put balloons in my breasts as a surprise so that when he fondled them they exploded. But it didn't work the first time so I let Colin in on the joke.

"Next time, he put pins in his fingers so he burst them when he grabbed me. It certainly startled the crew."
