Drew Carey
Kristie Alley

Christian Bale, for "The Mechanic"
ewwwww

Kirstie Alley
Marie Osmond

uumm... most of them?
their professional trainers & nutritionists practically live with them lol

Pretty much all of them at some point...

Is this really motivating for people? these people aren't 'regular' people with regular jobs to fit their weightloss into. Plus personal trainers at their beck and call?

Also Pauline Quirk had a gastric band

and Renee Zellweger looked awful and way too thin.

Sorry, maybe I misread the subject matter?:huh:
I think celebrities are those people a lot of people look up to (don't ask me why but they do) and if they inspire just one overweight person out there to try and lose weight then I think that's a good thing IMHO.

Christian Bale, for "The Mechanic"
ewwwww

Scariest images ever. That man is one dedicated actor.
