Jennifer Aniston shows off her tight tummy in a new ad for Smart Water.
"Working out feels great...afterwards," the ad's copy reads. "That's why I drink Smart. It's hydration I can feel. (And it's one part of my routine I never sweat.)"
"Sorry, but the last time I had baby food, I believe I was 1," she told People. "I've been on solids for about 40 years now."
