It's always the biggest soiree!

Bella Hadid, David Beckham, Lindsay Lohan, and Paris Hilton were just a few of the many celebs that attended the amfAR gala last night in Cannes, and the event raised a whopping $20 million for research!

Gigi Hadid's little sister slated on the red carpet, while Vicky B's husband made all the women swoon in a fancy tux. P-Hilty couldn't keep her hands off her man Chris Zylka, and Lilo brought the old Hollywood glamour.

Nicki Minaj, DNCE, Diana Ross, and Rita Ora performed, and a bunch of fashion industry peeps auctioned off designer dresses that grabbed $3.4 million.

As usual, Leonardo DiCaprio made the rounds, and Bella was spotted making her way over to his table. New couple alert? He does have a thing for supermodels and he's single, so we wouldn't be shocked if they got together.

What we would give to go to this party!
