Penn BadgelyLucky Penn Badgley, he gets to celebrate Halloween AND his birthday at the same time! Saturday night, Svedka Vodka presented the second event in their Adult Playground 2033 Series at 1 OAK. Blake Lively was sleek and stunning in her flight attendant costume and Michelle Trachtenberg deserved at least a double take in her elaborate Marie Antoinette ensemble.

At midnight, Penn was given a giant cake emblazoned with the Svedka fembot to celebrate his birthday. It was designed exclusively for him by our friend and uber creative designer, Ashley Simko.

These Gossip Girl stars along with countless others partied like it was 2033 as hosts Richie Akiva and Scott Sartiano helped Svedka continued it's path towards shaping the future of partying as we know it!
