Fans can agree that there was a certain "good-girl" quality about Melissa Joan Hart as she grew up in the Hollywood spotlight.
But in a new interview with Giuliana Rancic, airing tonight on E!, the Sabrina, the Teenage Witch star admits to making more than a few mistakes.
"It wasn't that I wasn't a bad girl or that I was too much of a good girl," she explains on Beyond Candid with Giuliana. "It was that I never got caught."
One of those mistakes, detailed in her memoir Melissa Explains It All, occurred before one very important photoshoot for Maxim magazine.
The night before, Melissa and a group of friends decided to attend a party hosted by Hugh Hefner The excitement (and nerves) would soon prove to be too much.
"You're in underwear so I was feeling a little shy," Melissa recalls. "I actually ended up rolling with some friends, doing some ecstasy and going in a limo to my first Playboy Mansion party. "
Once she arrived for work the next day, Melissa quickly regretted her behavior.
"I've never really done a man's magazine before," she said. "I didn't realize what kind of work went into a photoshoot."
And what about all those rumors surrounding her and Ryan Reynolds?
Melissa admits to having a very serious boyfriend when working on Sabrina, the Teenage Witch TV movie with Ryan. But after the then 17-year-old actor gave her a Bulova watch on their last day of shooting, Melissa couldn't ignore the attention.
"I chased him down, got in front of his car and just kissed him and then made out with him all night," she said. "Then I had to call my boyfriend the next day and explain it."
So that was it between the two of them?
"He came to New York to visit me," Melissa added. "But I think he wanted something more but I decided I was going to stick with my boyfriend."
