Speak Up: Should Slim Celebs Endorse Junk Food?

Naomi Campbell has been spotted shooting a commercial for Dunkin' Donuts in which she riffed on her anger-management issues. Naomi Campbell and Dunkin' Donuts- Now that's a match I didn't see coming. This reminds me of that Carl's Junior commercial in which Paris Hilton does a half naked strip tease washes the car. Another match I never would have guessed. So I am curious what you guys think about slim celebs endorsing products that aren't really going to keep us, the real people, slim (or healthy). Do you think a celeb should be able to endorse whatever they want even if they don't eat/buy/believe in the product they are endorsing? Or is it wrong for them to do so? Speak up and tell me what you think in the comments section below.
