"So the night before, I went to my very first Playboy Mansion party.  And it was the Mid-Summer Night's Eve party, where you're in underwear. … I was feeling, like, a little shy, so I actually ended up rolling with some friends, doing some ecstasy," Hart says in an interview with E!'s Giuliana Rancic, slated to air next week.
