That is definitely the smile of a happy camper!
Allison Williams just got engaged a few days before she hit up the Vanity Fair party on Sunday evening after the Oscars!
But instead of showing up with her fiancé Ricky Van Veen on her arm, Girlfriend came to the party with the newly predominant sparkler on her hand!
We can’t imagine why she wouldn’t say yes to that! LOLz!
Show off that fantastic ring, Ali!
