Gigi Hadid wore a tiny thong - and absolutely nothing else - to pose on horseback for the latest issue of Allure magazine.
In another arty photo, she sits upright on the horse with her long blonde hair covering her modesty.
She has slightly more clothes on in the cover photo - wearing a backless lace dress - and bright blue eyeshadow, next to the headline "Gigi Bares It All."
In the interview, Gigi opened up about her private life - revealing she loves to gaze at the shirtless pics boyfriend Zayn Malik often shares on his Instagram feed.
"Yeah, that's not hard to look at... I'll never complain about that," she told the magazine.
And she revealed it can be tough dealing with "haters" online who claims she is only famous because of her family's wealth and connections - her mother Yolanda Hadid is a former model and Real Housewives of Beverly Hills star.
"I always want to prove myself and to let people know I'm a good person," she said.
"A lot of people don't realize they're typing this stuff, and that's a lot of negative energy - regardless of whether we see it or not. People just don't realize the power of their judgment."
"My mom has neurological Lyme disease, which means it's spirochetes that are from bacteria that the tick has," she explained.
"The spirochetes are like little screws and kind of embed themselves in the brain tissue.
"When the disease affects the nerves in the brain, it's harder to detect because it's not in the bloodstream anymore. You have to do a special test for it."
