Rosamund Pike flashes a hint of side boob in a scarlet tulle gown at cannes ...

Stars flooded the red carpet to celebrate the closing night of Cannes Film Festival after many nights of glittering events. 

And Rosamund Pike looked stunning in a glamorous red tulle gown at the premiere of OSS 117: From Africa With Love on Saturday.  

The actress, 42, flashed a hint of side boob in the full-length gown as she stepped out on the final night of the festival.  

Rosamund stunned in the red dress that featured flared tulle detailing on the torso and also had a chiffon skirt that fell elegantly to the floor. 

Her backless ensemble also featured semi-sheer panels to either side of her torso to show off a glimpse of her cleavage as she posed for snaps. 

The Gone Girl star wore her blonde locks in a poker straight bob that framed her face well, and she wore a light palette of make-up for the occasion. 

Rosamund looked flawless as she worked her angles for the camera on the red carpet in the eye catching dress and white stilettos. 

Rosamund put on an upbeat display as she was joined at the event by her friend Sharon Stone. 

The basic instinct actress, 63, was a vision of Hollywood glamour as she arrived at the event in a strapless white thigh-split gown with a diamante bodice. 

The familiar actresses were seen enjoying a joke together while waiting to step onto the red carpet. 

Rosamund beamed as Sharon threw out a peace sign and a wave to a familiar onlooker in the crowd.
