Leif Garrett's been battling substance abuse problems for years, which is why he took part in Season 4 of 'Celebrity Rehab.' However, he stormed out of the Pasadena Recovey Center, later telling 'The Los Angeles' Times that producers encouraged him to relapse for dramatic purposes.

Last night Bob Forrest and Rachel Uchitel checked up on Garrett as part of 'Celebrity Rehab Revisited' (Sun., 9PM ET on VH1) and things did not go too well. Garret told the pair that he'd been taking lots of painkillers following a serious motorcycle accident, and then he admitted dabbling in marijuana and booze.

That's when Bob criticized Garrett's "cavalier and laissez-faire attitude toward alcohol," which did not sit well with the former teen idol. Saying "I really do not appreciate it," Garrett walked out. Again.

At first, Rachel Uchitel, alleged mistress of Tiger Woods, said she was opposed to the idea of starring on 'Celebrity Rehab With Dr. Drew.' But, she ultimately realized she needed help and decided to appear on the reality show, she said on 'The Early Show' (weekdays, 7AM ET on CBS).

On 'Today' (weekdays, 7AM ET on NBC), Rachel Uchitel, alleged mistress of Tiger Woods, disputes an article by the UK tabloid 'Daily Mail' in which she supposedly admitted to having an affair with the pro golfer.

Whoa! Sherri Shepherd, tell us how you really feel. Shepherd went on an extended rant about Tiger Woods' alleged mistress Rachel Uchitel on 'The View' (weekdays, syndicated), criticizing Uchitel for a series of supposed affairs with married men and wishing that a significant other would one day cheat on her.
