The 20-year-old model recently walked the red carpet at the French event in a stunning gown with an up-to-there slit. The dress turned out to be a bit more revealing than she probably expected, and it wasn't long before she accidentally flashed her underwear.
She told fans on Instagram that Cannes is her "favorite carpet," but we wonder if she still feels that way after her clothing mishap.

Bella also wore an ultra-revealing dress to last year's film festival, stunning the world in a breathtaking red gown. The brunette bombshell recently opened up about her love for modeling, and how she fears one day losing her career.
"I want to enjoy the ride because you never know where the end is," she admitted. "That’s what really freaks me out and worries me at night when I’m going to sleep."
