Celebrities are doing their part do endorse their favorite health brands and it looks like Jennifer Aniston is no exception. As I pointed out before, we have been seeing Jen walking around with smartwater [1] a lot recently. For a while I was just thinking the girl had a serious need to be hydrated, turns out, that was just half of it...

UsMagazine [2] is reporting that Glaceau is closing a deal with the former friend for her to be the face of its next worldwide advertising campaign. I think smartwater, water that's the envy of all water, and Jen, a woman that's the envy of all women, are a match made in heaven.

Jen tops the list of celebrity endorsements, but let's recap some other notables:

• Jenny McCarthy has been signed on to Weight Watchers [3].
• Dan Marino, former footballer extraordinare, is the face of NutriSystem for Men [4].
• Valerie Bertinelli will join Kirstie Alley doing Jenny Craig [5].
• And my personal favorite, Whoopi Goldberg for LA Weight Loss [6].
