Somehow, we are already on to the third season of Celebrity Fit Club. There is always somebody who is just a total mess, but this season, the casting folks have outdone themselves. First, they put Jeff "Kenickie from Grease" Conaway on the show, but he turned out to be so stuck in the throes of addiction that he went from an intervention (with Dr. Drew from Loveline, of all people) straight to rehab. Then Countess Vaughn ends up on the show and in the middle of a divorce. Bruce Vilanch is so overweight and unhealthy that the doctor sidelined him for two episodes (four weeks in the real world) to go through tons of heart testing. (He finally got the OK to work out again in today's show.) Conaway's replacement is Gunnar Nelson (as in son of Ricky, half of the hair band Nelson), who can't seem to get through a sentence without ripping his mom as an alcoholic or spouting some kind of therapy-speak or calling out his brand-new teammates for not working hard enough. Easy for him to say when he has like three pounds to lose. Tempestt Bledsoe (best known for her days on The Cosby Show) seems just plain uncomfortable to be there, and frankly, who can blame her? I've watched the past two seasons and found it pretty fun and somewhat inspiring -- it's one of those shows that gets me on the exercise bike, too, which is a plus. But so far, there is so much personal drama that it's not that much fun anymore.
