Rachel Bilson: 'Blue Valentine' in Cannes!

Rachel Bilson is lovely in an Isabel Murant leopard print dress as she hits the red carpet at the Blue Valentine after-party held at Palais Stephanie on Tuesday (May 19) in Cannes, France.

The 28-year-old actress celebrated the film with its stars, Michelle Williams and Ryan Gosling!

Earlier this week, Rachel was spotted at LAX for her flight across the pond!

FYI: Rachel finished her look with YSL shoes.
