Glitz! Glamour! Cannes!

Katy Perry, Bella Hadid and more glammed up for amfAR's 23rd Cinema Against AIDS Gala during The 69th Annual Cannes Film Festival on Thursday night.

Katy, who has been canoodling with beau Orlando Bloom during her trip to the south of France, attended the gala in a flamenco-inspired rose-trimmed dress by Marchesa. Hello senorita! The quirky singer later changed up her ensemble and took to the stage for a rousing performance at the star-studded benefit.

Bella donned a simple black gown before she walked the runway at the gala's disco-themed show, where she was joined by models Karlie Kloss, Jessica Hart, Natasha Poly, Lily Donaldson, Soo Joo Park, Toni Garrn, Isabeli Fontana, who all strutted their stuff down the catwalk in ’70s-themed looks.

While Bella stunned in a classic choice, Chanel Iman went for something bold and anything but classic for the red carpet. The model opted for a barely there netting dress. How cheeky!

Heidi Klum, Paris Hilton and Vanessa Paradis were also some of the notable names who put on their best duds for the swanky soiree!

The night's many events included an auction and during the high-priced activity, Oscar winner Leonardo DiCaprio auctioned off a one-week stay at his Palm Springs estate, Deadline reports.

The outlet reports that the trip can accommodate up to 12 guests but must abide by "house rules." The vacation is from January 16, 2017 at 3 p.m. until January 23rd at 10 a.m.

The site says that the hot prize went for 150,000 euros or approximately $168,157.50 dollars.

Sadly, a stay at Leo's house doesn't come with a stay with Leo. The actor made it clear his appearance did not come with the week-long purchase.
