Melissa Joan Hart: I Took Ecstasy

Feb. 17, 2014 -- Melissa Joan Hart wasn't the good girl you may have thought she was.

In a new memoir, she details her celeb hookups and drug use -- and now, she's opening up about them even more.

"It wasn't that I wasn't a bad girl or that I was too much of a good girl. It was that I never got caught," she told E! News. "If social media was around I think you probably would've thought of me in a different way a little bit."

The "Melissa & Joey" star, now 37 and the mother of three boys, explained that the night before her first racy photo shoot, she went to a party at the Playboy mansion. That night, she said, she experimented with ecstasy.

"I was feeling a little shy so I actually ended up rolling with some friends, doing some ecstasy," she said. "I was so excited. I was so nervous. It was so scary. I left really late at night [and] I think I rolled right up to the Maxim photo shoot."

Hart also delved into a story about one of her earliest romances, with her "Sabrina the Teenage Witch" co-star Ryan Reynolds. According to the TV star, she and Reynolds had a bit of a fling, culminating with him giving her an expensive watch.

"Ryan gave me a lot of great attention. He was really sweet and really warm and we had a lot of fun together," she said. After he gave Hart the watch, "I chased him down, got in front of his car and just kissed him and then made out with him all night. Then I had to call my boyfriend the next day and explain it. I think he wanted something more but I decided I was going to stick with my boyfriend."
