(Cover) - EN Showbiz - Hugh Hefner has accused his runaway bride Crystal Harris of lying about their relationship.

The 85-year-old Playboy magnate took to his Twitter page to discount her recent comments on the Howard Stern Show that they didn't have a good sex life.

Crystal told Howard that their amorous time together only lasted "like two seconds".

"Then I was l just over it. I was like, Ahh'. I just like, walked away. I'm not turned on by Hef, sorry," she said adding that they only had sex once.

"He doesn't really take off his clothes. I've never seen Hef naked."

But the magazine founder has hit back at her jibes by saying they did enjoy making love and that she was lying about their relationship.

"The sex with Crystal the first night was good enough so that I kept her over two more nights," Hugh wrote.

"Crystal lied about our relationship on Howard Stern but I don't know why. Maybe a new boyfriend? (sic)"

He also added that Crystal had "convinced me that she adored me. That was the first lie".

The 24-year-old model has denied she is dating television host Dr. Phil's son Jordan McGraw although she has admitted they are friends and has been seen with him on several occasions.

Hugh tweeted last month that he thought he "just missed a bullet" after Crystal called off their wedding just a few days before they were due to walk down the aisle. (C) Cover Media
