Buzz bellied up to the bar at Lacoste’s Fashion Night Out party where a civilian approached the bartender to ask what kind of Petron he was serving. Standing alongside the girl, “Gossip Girl” and “Weeds” actress Michelle Trachtenberg turned the other way and said to another boozing fashionista, “Can you believe that girl? She’s asking what kind of Patron they have. Um, they have Patron.” It’s worth noting Patron comes in reposado, silver and anejo.
