Crystal Harris dismissed her ex-fiancé Hugh Hefner's bedroom abilities saying, “I’ve Never Seen Hefner Naked.” The enraged 85-year-old Playboy founder has now hit back, saying Harris lied about their relationship.

After Crystal Harris claimed that the sex lasted “like two seconds,” Hefner retaliated: "Crystal lied about our relationship on Howard Stern but I don't know why." "Maybe a new boyfriend?" Hefner asked in a tweet.

Crystal also claimed that she and Hefner only had sex once in their two-year relationship, that she had never seen him naked and that Hefner was more into "couch cuddling and movie nights" than sex.

Hefner continued to call out Harris, 25, for what he pegged as dishonesty. "Crystal convinced me that she adored me," he replied to another follower. "That was the first lie."

After Crystal dumped Hefner in June, he moved on saying he is "happy to be in a better place with new girlfriends Anna Sophia Berglund & Shera Bechard."

"When I said, 'I missed a bullet' when Crystal left, I didn't mean I didn't love her," Hef explained. "I meant that I realized she didn't love me."
