(Cover) - EN Star Style - Jessica Szohr still sneaks in Cheetos even though she knows they are probably the worst thing for you.

The 25-year-old American actress appears in a campaign for beverage brand SoBe, as part of the SoBe Lifewater Skinsuit campaign. The beauty stars as a skinsuit model in the advertisement, which will appear in this months Sports Illustrated Swimsuit Issue and saw the actress shooting in the Costa Rican jungle.

Jessica worked hard to maintain her toned figure for the revealing shoot and watched what she ate, although she couldnt resist treating herself to her favourite cheese-flavoured snacks from time to time.

Im a huge fan of Cheetos. I had to cut those out a little bit because theyre probably the worst thing for you, so Ive cut those out majorly. I still sneak them in here and there, but that was a big thing for me to not have. I still allow myself to have them once in a while, she told okmagazine.com.

Despite depriving herself of the corn-based munchies, the gorgeous star did make sure she ate plenty of food after upping her exercise regime. Jessica found that working out made her ravenous.

I did a little bit of cardio, she explained. I did yoga, which gave me definition in my arms, and I was trying to have definition in my stomach. I worked out hard. After being in a gym, youre super hungry all the time because youre burning all these calories. (C) Cover Media
