Low blow: Crystal Harris hit former fiance Hugh Hefner below the belt when she appeared on the Howard Stern Show
Legendary Lothario Hugh Hefner is idolised by his followers around the world because of his decades of experience with model girlfriends.
But it looks like the the Playboy mogul will have to fight to save his reputation following explosive claims made by his former fiance Crystal Harris.
The glamour model could not resist hitting her ex-fiancé below the belt when she appeared on shock jock Howard Stern’s show today.
The 24-year-old did not mind fighting dirty despite the fact she walked out on Hefner days before their planned wedding in June.
Harris said sex with the 85-year-old Playboy founder lasted 'like two seconds'.
She added: 'Then I was just over it. I was like, 'Ahhh.' I was over it.
'I just like, walked away. I'm not turned on by Hef, sorry.'
She dealt a further blow to the ladies man's reputation when she revealed they had only been intimate once.

She said: 'He doesn't really take off his clothes. I've never seen Hef naked.'
Harris has already moved on from her relationship with the 85-year-old magazine publisher.
She has been spotted spending a great deal of time with the Jordan McGraw, son of Oprah Winfrey star Dr. Phil.
Despite denying rumours of a romance with the songwriter last month, she was spotted out with him at high-end New York bar Knave.

An bystander told People: ‘They were joined by two women who stayed for about an hour,
‘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.’
However she is not the only one to move on from their disastrous engagement.
Hefner has already announced he has two new girlfriends since their split last month.
He has previously dated up to seven models at once, with conquests including Brande Roderick, Izabella St. James, Tina Marie Jordan, Holly Madison, Bridget Marquardt, and Kendra Wilkinson.
