Melissa Joan Hart has written a memoir called Melissa Explains It All, in which she details her past drug use and celebrity hookups.

The Sabrina, The Teenage Witch actress talked with Life & Style about her tell-all memoir.

"I experimented with weed, Ecstasy, mushrooms and mescaline for about a year and a half," the 37-year-old told the magazine.

She admits to taking ecstasy in 1999 while at the Playboy Mansion and then on the ride home, making out with a girl. Then followed that by going to a Maxim photo shoot while high.

Hart says, "That was my third or fourth time on Ecstasy."

Though Hart experimented with drugs, she said she never got addicted. Paris Hilton once offered her some cocaine, but passed.

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

The actress also talked celebrity hookups, according to Huffington Post notes. She said she has slept with Nick Carter and Jerry O'Connell.

Hart called O'Connell a "man whore."

Since 2010, Hart has starred in the show Melissa & Joey.
