The Girls season-three premiere in NYC already had a lot of star power thanks to Lena Dunham, Allison Williams, Zosia Mamet, and Jemima Kirke, but it upped the ante with the list of stars who joined the party. From Joel McHale to John Oliver to Natasha Lyonne, everyone showed their support for the hit HBO show, and some even got cozy with the girls. At the afterparty, Seth Meyers and his wife laughed with Allison Williams, and returning guest star Andrew Rannells had Lena Dunham in a sandwich with an HBO exec. Thing got even more fun when celebrities posed in and around the G train subway car that was smack in the middle of the party.
