Crystal Harris, who called off her wedding to Hugh Hefner Tuesday, denies cheating on the Playboy founder with Dr. Phil's son.

Reports and rumors have it that 25-year-old Harris had a secret affair with Jordan McGraw, who were both spotted together at the Chateau Marmont in March. According to Life & Style magazine, McGraw was apparently seen 'kissing the blonde's shoulder and trying to hold her hand'.

Crystal's manager Michael Blakely denies the claim, saying That is absolutely not true. It's a complete fabrication.
