OSCAR-winning actress Charlize Theron and MONSTER co-star Christina Ricci took their on-screen romance so seriously - the actress's jealous boyfriend Stuart Townsend left the set fuming.

The film's director Patty Jenkins realised the two beauties were nervous about their love scenes so locked them in a room and told them to have a "lesbian party".

Jenkins tells British tabloid the STAR, "I had to do something to cut the ice, so I got them in a room, banished the crew and took in a bottle of tequila. I told them we were going to have a lesbian party.

"I just watched them get on with it, in no time they were totally in to each other.

"At first they were just kissing, then Charlize had Christina bent over and was slapping her a** with a tennis racquet, Christina was moaning and licking her way up Charlize's leg. Very horny."

She went on to say, "After that they were lovers 24/7, they never slipped out of character - they were wild.

"Charlize's boyfriend visited but after he saw what she was like he left, I think he found it hard to deal with."
