How unbelievably gorgeous is Kristen Stewart?!

The 22-year-old Twilight actress hit the red carpet premiere of Robert Pattinson’s new film Cosmopolis in Cannes, France on Friday, and looked positively stunning in a floor-length Reem Acra gown. Adding just a touch of sexiness, Stewart’s dress had a plunging neckline, and see-through lace back. Tres chic!

Though she didn’t pose with her 26-year-old beau, she was definitely in good company.

Kristen, who was at the Cannes Film Festival to promote her own project, On the Road, was joined on the red carpet by Pattinson’s BFF Tom Sturridge, 26, who is currently expecting his first child with fiancee Sienna Miller, 30.

Earlier this week, it was Rob’s turn to support Kristen as he attended the premiere of her new film, On the Road, the film adpatation of Jack Kerouac famous novel of the same name. It also stars another real-life couple, Kirsten Dunst and Garrett Hedlund.

However, Friday was all about Rob, and the premiere of his film, Cosmopolis. Check out the trailer below.
