Melissa Joan Hart, the girl-next-door child star, is revealing her secret wild side in an explosive new tell-all – and Life & Style has the exclusive first look! From drug-fueled nights on the town to steamy affairs with co-stars, the 37-year-old actress has a lot of dirt to dish in her new book, Melissa Explains It All, on shelves Oct. 29—but first she’s spilling all in the new issue of Life & Style, on newsstands now. “I experimented with weed, Ecstasy, mushrooms and mescaline for about a year and a half,” Melissa admits to the magazine. One of her crazier adventures involved taking Ecstasy at the Playboy Mansion in 1999, making out with a girl in the limo ride home — and then heading to a Maxim photo shoot while still high! “That was my third or fourth time on Ecstasy,” she reveals. Thankfully, her dabbling never led to addiction. In fact, when Paris Hilton offered her cocaine, she turned her down (a rep for Paris denies the claim). “I was kind of running with a bad crowd,” she explains. In the end, “I just didn’t enjoy taking drugs. I don’t like the loss of control.” The actress also revealed past make out sessions with Jerry O’Connell (calling him a “man-whore”) and Backstreet Boy Nick Carter. But not all Hollywood hotties were on her lust list. She twice tried to kick Ashton Kutcher out of her parties for making “smartass remarks.” “Ashton and I just didn’t get along,” she recalls.
