But Bella's latest sexy stunt at this year's fest just took things to a whole new level.
A video posted to Instagram shows Bella partying on a yacht alongside fellow supermodels Emily Ratajkowski and Hailey Baldwin. As they all dance together while having what looks like a pretty amazing time, Bella decides to kick it up a notch.
She playfully cups EmRata's glorious boobs, causing the DKNY lingerie model to totally crack up and even blush a little. All the while, Baldwin keeps dancing in an oversized sweatshirt as if this epic happening was just a typical dance-off for the three gorgeous pals.
For the record, EmRata was totally cool with it. She's the one who posted the video to Instagram, after all.
But the whole crew has been hitting Instagram with pics at Cannes that are going to make it hard for anyone to pay attention to the movies. See some more Cannes action below:
