Jessica Szohr SOBE AdsWearing nothing more than lizard-scale body paint, 'Gossip Girl' actress Jessica Szohr strikes a sultry pose as the face of the new SoBe Lifewater campaign. She shed her inhibitions in the Costa Rican jungle, admitting she wasn't that shy about baring it all.

"The photos were done so tastefully and beautifully. I felt really good," she tells PopEater.

The only "scary and uncomfortable" thing about the photo shoot was trudging through the mud and waterfalls in the middle of the rain forest sans clothing. But Szohr couldn't be happier with the sexy photos, which will appear exclusively in the Sports Illustrated Swimsuit Edition hitting newsstands Feb. 15.

Szohr prepared for the shoot by doing intense cardio and weight workouts -- and cutting back on her junk food vice. "Instead of totally cutting [Cheetos] out and driving myself crazy, I would sneak them in here and there," she reveals.
