VIDEO: Rachel Uchitel On Love Addiction - 'I Knew That I Needed Help'

Uchitel, the Manhattan hostess who was the first mistress reported in the Woods infidelity saga, appeared on the show in a sexy black skirt  and pumped-up lips alongside her Celebrity Rehab mentor, Dr. Drew Pinsky. 

Uchitel was quoted by the Daily Mail earlier this month saying she'd "never ever imagined in my wildest dreams that I would be caught up in a scandal like this," as well as admitting she'd "plunged headfirst into relationships which I should never have been in.”

Uchitel also said she was being treated for addiction to Ambien and other prescribtion medications, which she did not identify.

Pinsky said that Uchitel's condition is partly triggered by traumatic events in her past, such as the premature deaths of her father and her one-time fiancée Andy O'Grady, who perished in the September 11, 2001 attacks on the World Trade Center.

"I'm a completely different person now than I was before I went on the show," Uchitel said. 

In an earlier exclusive interview with RadarOnline.com, Uchitel foreshadowed what she would say on Today. "People think it is a moral issue if somebody falls in love, all over the place," Uchitel told us.

"But it is not an excuse for anyone's behavior.
