'I'm dreading mummy & daddy watching me snog Carmen Electra'

HER first screen kiss is a passionate clinch with one of the sexiest stars in Hollywood.

It's ex-public schoolgirl Stephanie Blacker's big break... but she's dreading her parents seeing her up there on the big screen. For one thing she's wearing some seriously revealing underwear and strapped to a chair. For another, she's kissing Baywatch babe Carmen Electra.

"My parents thought I would have a career in horseriding, so seeing me half-naked in the cinema having a lesbian kiss will take a bit of getting used to," says Steph, who stars with Carmen in raunchy new British comedy I Want Candy. "They haven't seen the film yet, but when they do I'll be hiding behind my seat during the sex scenes. But my brother Dan couldn't believe it when I told him I'd kissed Carmen. He was so jealous." Steph, 23, whose father Philip is a former jockey and mum Susan an antiques dealer, went to pounds 20,000-ayear St Mary's School, in Wantage, Oxon. "I grew up surrounded by horses and competed in show- jumping and dressage events for England's Under-18 team," she says. "But dad said I had to choose between horses and being an actress and I went to drama school." In I Want Candy, which has just been released, Steph is a receptionist roped into an adult movie starring Carmen. "It felt like an age waiting for Carmen to kiss me," says Steph. "But it was incredible. She oozes sex appeal and made me feel very comfortable. And she has such a dirty sense of humour, she put us all at our ease." Since the sexy screen kiss, Carmen has been linked to Eighties rocker Joan Jett, 48.
