Melissa Joan Hart's new autobiography, "Melissa Explains It All: Tales From My Abnormally Normal Life" (out October 29), reveals that the actress was yet another child star who dabbled in drugs, but unlike many others, her life did not become a cautionary tale.

"I experimented with weed, Ecstasy, mushrooms and mescaline for about a year and a half," Melissa tells Life & Style, in anticipation of those revelations coming out in the book. One of Hart's craziest 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 says.

"I was kind of running with a bad crowd," she reflects. In the end, "I just didn't enjoy taking drugs. I don't like the loss of control."

Other admissions in the book include make-out sessions with Jerry O'Connell (who she calls a "man-whore") and Backstreet Boy Nick Carter. And her biggest Hollywood feud? That would be with Ashton Kutcher! "Ashton and I just didn't get along," she says, adding that she tried -- and failed -- to get him kicked out of at least two parties.
