Michelle Williams celebrated her second Cannes premiere at a party in a private villa in the hills above the French city.
And guess who stopped by? Brad Pitt!
Pitt, 44, chatted briefly with Williams, 27, by the fire at the Villa St. Antoine in Vallauris, France. The party – for about 200 people – celebrated the premiere of Synecdoche, New York, Williams’s film with Philip Seymour Hoffman, Catherine Keener and Samantha Morton.
At the party, which featured tents on the lawn, Pitt drank champagne and talked for nearly an hour with longtime friend Keener. He showed her pictures of his kids on his iPhone and talked about how excited he was for the birth of his twins with Angelina Jolie. (Keener clearly was excited too – she kept announcing to callers on her own cell phone that she was chatting to “BP.”)
Pitt also took the opportunity to practice the second language in the Jolie-Pitt household, chatting briefly – in French! – to a guest.
