Talk about a low blow. After dumping Hugh Hefner just days before their June 18 wedding, Playboy model Crystal Harris opened up about their sex life during a Tuesday interview on Sirius XM's Howard Stern Show.

"[It lasted] like, two seconds," Harris, 25, said, dissing the famed men's magazine editor. "Then I was just over it. I was like, 'Ahh.' I was over it. I just, like, walked away. I'm not turned on by Hef. Sorry."

The hurtful claims shouldn't be too surprising given the fact that Harris partied with VH1 reality star Heidi Montag on what would have been her wedding day. Adding to Hefner's heartache was Harris' "hot and heavy" affair with Dr. Phil McGraw's son Jordan, 26. (In June, an insider told Us Weekly that Harris and McGraw had been together six months prior to her split with Hefner.)

Still, Hefner is wise enough to know that everything happens for a reason. "After all is said and done, staying single is probably the best," he tweeted in June. "I think I just missed a bullet."
