The 19-year-old model is steaming it up in Guess' 2015 Spring campaign, where she poses topless in only a pair of jeans with a large floral print on the leg.
The other pics show the blonde bombshell wearing sheer skirts, a denim jacket with absolutely nothing at all underneath and even a totally sheer knit top..
The daughter of "Real Housewives of Beverly Hills" star Yolanda Foster was discovered by Guess co-founder Paul Marciano at just four years old, and she was named the face of the brand in 2012.
"Going on 15 years as a Guess Girl, this may be my favorite campaign yet," Gigi said in a statement. "The collection is so effortless to wear, and fits perfectly in any summer environment. I couldn't think of a better place to shoot the campaign then where we did - on the beaches of my hometown in Malibu! So fitting."
Hadid is no stranger to posing in next-to-nothing!
