Tiger Woods' most favorite mistress—at least, based on rumors that he paid her millions to keep her trap shut about their relationship—Rachel Uchitel was on the Today Show to explain how she has "a hole I am trying to fill in my heart." The former NYC nightclub hostess (and current Park Avenue apartment owner) is on the upcoming season of Celebrity Rehab and also said, "I had no idea that love addiction existed. I sort of brushed it off."

Dr. Drew Pinsky, who runs the rehab facility, confirmed, "She has been through horrific traumas throughout her life that imprint on the way she’s viewed relationships." One would be the death of her father, who, 20 years ago, was found dead from a cocaine overdose on his Alaska estate. The other is the death of her fiance during the World Trade Center attacks on 9/11.

Uchitel, whose notoriety due to Tiger Woods is not mentioned at all on the Celebrity Rehab website, was also addicted to prescription drugs but sought help so other women could learn from her experience, "I went on the show because I knew at the time I needed help. I didn’t know what was going on with me. I knew I needed help. The issue I have with relationships is related to a hole I am trying to fill in my heart … I have since changed the path of my life."
