Gossip released their fifth album, A Joyful Of Noise, earlier this week.
Bérénice Béjo officially opened the 2012 Cannes Film Festival at a ceremony, which was held inside the Palais des Festivals.
The Artist actress looked every inch the screen siren in a scarlet red Louis Vuitton gown.

The Help star Jessica Chastain went for a cool and understated white Alexander McQueen creation - a fitting look for the searing heat of the French Riviera.
The real talk of the red carpet, however, was jury panelist Diane Kruger's breathtaking Giambattista Valli Couture gown - a flowing, draped mint green dress that billowed in the wind as she walked.
Lana Del Rey also made an appearance at Cannes. The singer wore a simple black strapless gown for the occasion.
Meanwhile, as the stars arrived for the opening ceremony, Sacha Baron Cohen began his reign of controversy in the name of promoting his new movie, The Dictator.
The spoof actor enlisted the help of George Clooney's ex, Elisabeta Canalis to help him drum up publicity. The pair - with Baron Cohen dressed as The Dictator - were seen frolicking on a yacht together, enjoying Champagne and seductive massages. But the romance was short-lived. The Dictator visibly tired of the Italian model, causing gasps from onlookers after he was seen dragging her around the deck by her feet. Canalis is then seen being taken deck, before one of Aladeen's advisors re-emerged with what appeared to be a black body bag, which was then thrown overboard.
Rest assured however, no models were harmed in the making of the stunt - Canalis was later seen enjoying some down time on the beach before heading back to her hotel.
