She attended the premiere of La Passion de Dodin Bouffant in this canary yellow, draped dress by Zuhair Murad. The gown featured a high slit, sexy chest cutouts, and bejeweled shoulders.
It also had these voluminous sleeves Heidi really seemed to love, because she kept whooshing them around while posing for pics.
But the movement caused her top to shift β and when she resumed taking photos, part of her nipple was exposed.
But Heidi stayed calm and carried on posing for photos!
She also shared pics of the moment on Instagram, which she simply captioned, "CANNES π."
Yess! π Way to handle a wardrobe malfunction, Heidi!
