Keeley Hazell has stopped trusting men since she unwittingly became the star of a homemade sex tape.The 20-year-old glamour model filmed the X-rated footage with her ex-boyfriend, Lloyd Miller, during a holiday to Majorca last year.Earlier this month, the tape - which shows Keeley involved in a variety of sex acts - was leaked onto the internet and to a British newspaper and the busty model admits the experience has shattered her faith in men.She told Britain's Zoo magazine: "It has taught me some valuable lessons - such as who to trust. I don't want to make the same mistake again. If any men try to chat me up they should remember that."People don't understand - you may think because I'm a topless model I'd be happy. But this was something private, between me and someone I thought I trusted."I didn't even want to leave the house - it's been so horrible."
