London, May 20 (Inditop.com) Actress Jennifer Aniston shows off her toned abdominal muscles in a series of mineral water ads.

In the ad, the 41-year-old is seen in a skimpy work-out gear, drenched in sweat and holding a bottle of SmartWater, the mineral water brand she has been endorsing since 2007.

The caption of the picture reads: “Working out feels great… afterwards. That’s why I drink Smart. It’s hydration I can feel. (And it’s one part of my routine I never sweat.)”.

Yoga and fitness buff Aniston had recently shot down reports that she is now on a baby food diet to stay fit.

“I’ve been asked lately, ‘Jen, what’s this baby food diet all about?’ I kept thinking, ‘That’s the strangest question ever’. The last time I had baby food, I believe I was one. I’ve been on solids for about 40 years now,” she said.
