Who would have thought being engaged to Playboy founder Hugh Hefner would be so rough? Well, for Crystal Harris it wasn’t her dream come true, especially in the sack.

According to Hef’s ex-fiancée, Hefner, 85, only lasted ‘two seconds’ the one time they had sex.

“Then I was just over it,” the 25-year-old told Howard Stern on his radio show. “I was like, ‘Ahhh.’ I was over it. I just, like, walked away. I’m not turned on by Hef, sorry.”

Harris reportedly also never saw Hefner naked. He “doesn’t really take off his clothes. I’ve never seen Hef naked,” she said.

Hefner made sure to clear up his runaway bride’s comments. On Tuesday night he tweeted, “Crystal lied about our relationship on Howard Stern but I don’t know why. Maybe a new boyfriend?”

He later replied to a follower by writing, “Crystal convinced me that she adored me. That was the first lie.”

One thing that seems to ring true is Hefner’s feelings when he was with Harris. He said, “When I said, ‘I missed a bullet’ when Crystal left, I didn’t mean I didn’t love her. I meant that I realized she didn’t love me.”

All this banter hasn’t slowed down Harris or Hefner’s social lives. Recently, Harris has been linked to Dr. Phil’s son, Jordan McGraw, and Hef has two new girls on his arms, Anna Sophia Berglund and Shera Bechard.
