Kelly Brook has confessed she still gets nervous about appearing scantily clad on camera as she attended the premiere of funnyman Keith Lemon's risque new film.
The actress and model, who regularly poses for photo shoots in lingerie and swimwear, wears skimpy underwear, suspenders and a revealing bikini during the comedy.
Dressed in a figure-hugging lace gown for the premiere in London's Leicester Square, Brook said: "It's horrendous, I didn't know I'd be doing that but he got everyone doing all sorts."
Brook plays herself in the movie, in which the moustachioed star finds fortune after inventing the Lemon Phone - a bog-standard mobile phone with a lemon stuck on it.
"We all just wanted to do a film with him. He's just funny, isn't he, there's no one like him," she said. "He's crazy. He never sticks to the script, he always comes off the script so you never know which way he's going to go and you just have to keep a straight face."
Lemon - the alter ego of entertainer Leigh Francis - managed to secure cameos from names such as Gary Barlow, Ronan Keating, David Hasselhoff and ITV2 Celebrity Juice co-stars Fearne Cotton and Holly Willoughby.
Dressed in a white suit with feather wings for the Odeon West End premiere, he said: "They got paid nothing. Most of them just wanted to come out and have a bit of fun and I think they all had fun."
But he said he was not planning to head to Hollywood just yet.
"They'd probably say 'We can't tell what you're saying so we don't want you'," he said. "I'm not bothered about fame. I'll still eat Scotch eggs."
