Hollywood adds glam to Cannes

Hollywood hotties like Jennifer Lopez added glam to the 63rd Cannes film festival on Thursday.

Jennifer looked pretty in a pink Roberto Cavalli Couture gown and Chopard diamonds as she attended amfAR's annual Cinema Against AIDS gala.

While JLo glowed in pink, actress Marion Cotillard looked somber in black. Somehow, the outfit makes her look as if she's pregnant.

Diane Kruger stuck to this classic Chanel gown in contrasting black and white. Jewellery from Chanel and Sergio Rossi heels completed the fab look.

Jury member Kate Beckinsale puts her best foot (shod in Sergio Rossi satin platform slingbacks) forward in this Armani gown.

Blonde beauty Elizabeth Banks looks smashing in this Atelier Versace halter dress.

Singer Mary J Blige looks very lady-like in this Gucci pearl micro beaded one-shouldered gown.
