Gossip Girl's Jessica Szohr left the Upper East Side for the jungles of Costa Rica to shoot her new campaign for SoBe Lifewater, in which she wears nothing more than some strategically placed body paint! The pictures will appear in the Sports Illustrated Swimsuit Issue, available on newsstands Feb. 15. I spoke to Jessica yesterday about her new gig, and she said that while she wasn't nervous about stripping down, she did get some advice from last year's model. Jessica said, "My friend Ashley Greene did it last year . . . and I remember thinking, 'Oh my god that's paint on you?' Because it actually looks like a swimsuit." She also chatted about her hit CW show, saying she'd love for her character, Vanessa, to hook up with a "Brooklyn guy" next. Check out today's PopSugar Rush for our full interview with Jessica!
