The Sєxiest sisters in town! Gigi and Bella Hadid hit the runway at Tommy Hilfiger’s New York Fashion Week show on Monday, Sept. 14, where the cheeky beauties bared their bums in teeny ʙικιɴιs

Print modeling pros, the budding supermodel sisters—who are the daughters of former model and Real Housewives of Beverly Hills star Yolanda Foster—both owned the runway in their barely there ensembles. While Gigi, 20, donned a printed two-piece with a multicolored hat and a statement necklace, Bella, 18, worked a mesh top and drawstring pants—which she eventually lost, just in time for the finale.

When Gigi and Bella left the boardwalk-style stage (complete with water!) and wrapped the show, they did so holding hands and without pants, giving the audience a prime view of their perfect posteriors. Last but not least, the blonde beauty planted a kiss on her little sister’s cheek.

Teen Vogue managed to snap a pic of the ladies backstage, too, where they smized for the camera side by side while lounging in white robes.

But Tommy wasn’t the only double Hadid feature! Bella and Gigi also shared the runway at the Diane von Furstenberg show the day before. DVF took to Instagram to document the cute moments between the sisters backstage, which included more cheek kisses and standing around with their hair in pin curls backstage.
