Playboy star Crystal Harris has tried to defend the comments she made about ex Hugh Hefner.

The 25-year-old recently appeared on Howard Stern’s radio show and made comments about her sex life with the Playboy founder before they split and said he lasted about ‘two seconds’ in bed.

Harris has been criticised for the comments and has now taken to Twitter to defend herself.

She wrote: “The choices we make in life are half chance. So are everyone else’s.”

She then added: “The Stern interview scared me, he’s harsh. I was unprepared and blurted out things I shouldn’t have said, I’m sorry.”
