Wearing a red leopard print dress with a split up to her hip and a slash across the chest, Jessie J certainly grabbed attention at the amfAR Gala at the Hotel du Cap in Cap d'Antibes last night.

The Voice UK judge tweeted a photo of her outfit with the caption: "Red Carpet done :) now to sing to the most beautiful group of people I've ever seen. Woah! Let's raise some money for charity."

Jessie J performed at the star-studded charity night and entertained the A-list crowd in attendance.

However, the 'Price Tag' singer wasn't able to head to the after-party as she had an early start.

Jessie J tweeted: "I can hear the after party music :( BUT I gotta be up EARLY so its bedtime for me. Thank you for having me #amfar #cannes Goodnight x"
