Guess who was hanging out with Tim Roth and Dennis Hopper? To find out,
You probably already figured it out, but the answer is: Mario Batali. He was hosting a cocktail party at Enoteca San Marco at the Venetian Hotel in Las Vegas.
Personally, I love the way this photo is awkwardly posed, as if Roth and Hopper were big fans who needed to have their picture taken with Batali, or maybe they're a happy family on vacation?
