 Hugh Hefner is striking back at ex-fiance Crystal Harris after she said she was grossed out by their sex life on “The Howard Stern Show” today. 
 
 The Playboy mogul tweeted, “Crystal did a crazy interview with Howard Stern today that didn’t have much to do with reality. Is she trying to impress a new boyfriend?” 
 
 In the segment, Harris told Stern that she never saw Hefner naked and was disgusted by their sex life, saying, “[It lasted] like, two seconds… I’m not turned on by Hef. Sorry.” 
 
 But Hefner says it’s all lies. 
 
 He tweeted, “The sex with Crystal the first night was good enough so that I kept her over two more nights.” 
 
 “Crystal lied about our relationship on Howard Stern but I don’t know why,” he added. 
 
 Harris partied with Heidi Montag on her would-be wedding day, and later tried to hawk her engagement ring. 
 
 Watch her interview below.

 Crystal Harris is moving on from Hugh Hefner, but not without taking a few parting shots at her former fiancé.Harris, 24, said Tuesday on Sirius XM Radio's Howard Stern Show that sex with the 85-year-old Playboy founder lasted "like two seconds.""Then I was just over it," she says. "I was like, 'Ahhh.' I was over it. I just like, walked away. I'm not turned on by Hef, sorry."She adds that they had sex just once."He doesn't really take off his clothes," Harris says. "I've never seen Hef naked."Now that Harris has parted ways from Hefner, she is spending a great deal of time with Dr. Phil's son Jordan McGraw.Although denying a reported romance with the songwriter in June, Harris was spotted out with him recently at Knave, the upscale and dimly lit bar at Le Parker Meridien in NYC."They were joined by two women who stayed for about an hour," an onlooker tells PEOPLE. "Crystal was drinking mojitos and laughing, and Jordan was sipping a drink on the rocks. But once their friends left, they really settled in and seemed more and more comfortable."
– Since ditching Hugh Hefner at the altar a couple of weeks ago, Playboy playmate Crystal Harris has only added to her frank critique of Hefner's lovemaking shortcomings, telling Howard Stern that sex with Hef was over in "like two seconds," reports People. "Then I was just over it," she says. "I was like, 'Ahhh.' I was over it. I just like, walked away. I'm not turned on by Hef, sorry." Harris also said that Hefner never takes off all of his clothes ("I've never seen Hef naked") and that they had sex only once. But Hef isn't taking any of this lying down. In tweets that have apparently since been deleted, Hefner accused Harris of lying during her Stern appearance, adding that he didn't know why she would do such a thing, Gossip Cop reports. “The sex with Crystal the first night was good enough so that I kept her over two more nights," he continued. “Crystal did a crazy interview with Howard Stern today that didn’t have much to do with reality. Is she trying to impress a new boyfriend?”
