The 33-year-old former Glee actor actually dressed up as Jared and replicated one of his favorite Saint Laurent jackets by bedazzling one himself! One of Mark‘s friends even dressed up as our resident photographer Justin Campbell.
Mark was seen having fun with the Nerf Zombie Strike toy at the party. All of the guests who entered the venue got the chance to shoot the zombie target in the maze outside as well!
Other guests at the party included Chord Overstreet, Drew Van Acker, Grey Damon, Giles Matthey, Edi Gathegi, Chris Galya, Josh Henderson, Jayson Blair, Luke Grimes, Tony Revolori, and social media star Logan Paul.
