Justin Bieber has been doing some major campaigning this week for the release of his new album, Believe. But talk show host and Bieber-spoofer Jimmy Fallon just released a new album earlier this month and it will Blow Your Pants Off.
For some cross-promotion, J&J got together to compete in an ultimate showdown of awesomeness, comprised of lasertag, pushups, Marco Polo, and holding their breath.
The video footage of this event aired last night on Fallon's Late Night program, only a couple of hours after the two went live for an interview on the YouTube Presents channel.
Can you guess who won?
