While planting a kiss on the Hollywood actress, Bella's nude underwear was exposed as the thigh-high split of her gown moved, with the same issue occurring once more when she made moves to show photographers the back of her dress. The red carpet saw her make quite the bold statement with extreme smoky eyes in a teal green that corresponded with her bottle green gown!
Day 2 at the prestigious Cannes Film Festival saw some more film screenings and many more lovely outfits on the red carpet.
So who do we expect to grace the red carpet this year?
This marks the beginning of a week-long exhibition of the world's most fashionable stars, and of course the films they're promoting.
And while the women ruled the red carpet, actor and jury member Will Smith was not about to be left behind.
Hailey, 20, also posted a photograph of the three women on the yacht in the south of France, where the 70th edition of the Cannes Film Festival is now being staged.
We think she looks a little bit like the red dancer emoji, don't you?
The Jacket star Adrien Brody also cut a fine figure on the red carpet accompanied by his girlfriend Lara Lieto.
While they might not be in any of the films screening at this year's festival, the models seemed to be the main attraction at the opening gala.
A pair of encrusted danglers and a ring from the jewellery brand De Grisogono were the only accessories she chose to wear. "I was probably 14 years old the last time I watched three movies in one day".
Hadid's "big risk" previous year paid off as she suffered no noticeable wardrobe malfunction besides the essential malfunction that is the nature of a dress cut to display most of the wearer's torso as well as hips, up to the waist.
After all, a whole lot has changed since she first started walking the step and repeat, most notably how heavily scrutinized and dissected by the media every outfit, hairstyle, and makeup look has become.
