Hollywood's most fashionable, in-the-know celebs have yet another thing in common: They're all fans of an under-the-radar Italian footwear label we're about to spill all the deets on. Sorry, not sorry to the A-listers who wanted to keep this one their own little secret.

Gigi Hadid was most recently seen in this hush-hush brand's shoes. The supermodel wore a Frankies Bikinis two-piece lounge set with a pair of brown, shearling-lined buckle slides that, no, weren't Birkenstocks. Instead, Hadid's slip-ons were from M.Gemi, an Italian footwear label that also counts Eva Longoria, Lucy Hale, Camila Cabello, Diane Kruger, Eiza González, and Gal Gadot as fans, per a press release.
