John rocked a Louis Vuitton backpack as the two headed to their separate rides after the gig just ahead of New Year’s Eve.

The two will be collaborating on a special show of stand-up and musical sets called Controlled Danger at the Forum on New Year’s Eve (December 31) in Los Angeles.

“I drank so much Red Bull tonight that I’m not even wired anymore. It’s just frantic silence. Like a safe exploding underwater,” John tweeted early on Friday morning (December 29).
