Crystal Harris was in a relationship with Hugh Hefner (60 years her senior) from Jan 2009- June 2011. He proposed to her on Christmas Eve of 2010. But she broke off the engagement just five days before their planned wedding. On "The Howard Stern Show" Crystal discussed her sex life. "[It lasted] like, two seconds. Then I was just over it. I was like, 'Ahh.' I was over it. I just, like, walked away. I'm not turned on by Hef. Sorry."
Crystal added in an interview with "Entertainment Tonight," "I wasn't the only woman in Hef's life. I didn't feel comfortable in my heart knowing that and getting married to him, because a marriage is between two people." And "the mansion schedule is so strict " you know, movie night, home by 6 o'clock, every Friday, Saturday and Sunday for movie nights."
Hefner later responded that Harris was lying. "Crystal convinced me that she adored me. That was the first lie." There were also rumors that she was cheating with one of Dr. Phil's sons.
However, as of June 2012, she and Hugh Hefner reunited. She tweeted, "Yes, I am his #1 girl again. Yes we are happy. Hope that clears up any confusion! XO."
