Here’s Gigi Hadid’s just-as-ridiculously-hot younger sister (also a model/socialite), Bella Hadid, dropping everyone’s jaw and stealing the show and inducing a serious drool-fest at yesterday’s 69th Cannes Film Festival premiere for The Unknown Girl with a stunning and drop dead sexy display of her red hot body in one hell of a skimpy/revealing dress… sweet baby Jesus! Get a load of that awesome braless cleavage! And those killer legs! And the fact that she’s not wearing any underwear! C’mon, you know she isn’t. I mean, you can’t show off that much leg and skin action wearing any underwear. Alright, too much blabbing. Enjoy the sizzling photos and check out the rest after the jump!
