Jennifer Aniston SmartWaterIf you've got it, flaunt it -- and Jennifer Aniston does just that in her new SmartWater campaign.

The actress, who has been a spokesperson for the brand since 2007, shows off her abs in a new ad for the water.

"Working out feels great ... afterwards," the tagline for the photo reads. "That's why I drink smart. It's hydration I can feel. (And it's one part of my routine I never sweat.)"

"Jennifer truly embodies what SmartWater is all about as she combines substance and style," one executive said when Aniston signed on to represent the company three years ago.

The 41-year-old star is famously fit, and is often seen gallivanting on the beach in small bikinis. Recently, she's was hit with rumors that she was on a baby food diet, which she quickly dispelled.

"Sorry, but the last time I had baby food, I believe I was 1. I've been on solids for about 40 years now," she told PEOPLE.
