Katy Perry turned up the heat as she arrived at the amfAR Gala in a striking dress.

The Firework singer wowed at the glitzy event in a flamenco-style floor-length gown with frills.

Katy made quite the impression, posing with her hands on her hips and her dark hair slicked back.

She pouted for the cameras and a splash of red lipstick added some extra Sєx appeal.

Katy, 31, no doubt had one special admirer at the event – her boyfriend, Orlando Bloom.

The pair arrived separately as they try and keep a lid on their blossoming romance, despite being seen on a number of romantic dates while in Cannes.

Brit actor Orlando looked very dapper in a black tuxedo and bow tie.
