Crystal Harris: Hef's Lifestyle Wasn't For Me

Just a day after officially calling off her June 18th wedding to Hugh Hefner, Crystal Harris has revealed why she made the shocking decision to walk away.

The 25-year-old playmate phoned "On Air with Ryan Seacrest" earlier today (June 15) to dispel any rumors of a much-reported nasty breakup.

Crystal explained that the split was agreed upon by both sides, as she told, “It was mutual between Hef and I. There was no fight, we sat down and we talked about it.”

Harris furthered her reasoning for the pre-wedding exit, revealing that "for a while I’ve been having second thoughts about everything. I haven’t really been at peace with myself lately. I didn’t think it was really fair to him.”
