Posty got into Game Day mode at the Bud Light Super Bowl Music Fest on Feb. 1. The singer tends to have a beer in his hand onstage, and he went the extra step during this concert to rep his love of Bud Light on his shirt. Hahn calls the look a "shout out to Bud Light and a shout out to the Super Bowl."

"He loves beer pong, everyone knows that. He plays it all the time, he's really good," Hahn tells E! News. "I get inspiration from what he's doing like the Super Bowl party. There's beer, so that becomes the inspiration. He's the inspiration for everything. It's all stuff that he likes."
