Michelle Williams is amfAR Gala Gorgeous

Michelle Williams steps out in style in Sonia Rykiel at amfAR’s Cinema Against Aids gala held at the Hotel du Cap on Thursday (May 20) in Antibes, France.

The 29-year-old actress accessorized with Ferragamo shoes and a Chanel clutch for the event.

Michelle and her Blue Valentine co-star, Ryan Gosling, looked to be super close at events held at Cannes for their new movie, but both parties deny they’re more than friends.

“He is cozy with everyone!” Ryan‘s rep told People, while Michelle‘s rep says simply, “They are not dating.”
