Panic! at the Disco's Brendon Urie Stars In Fall Out Boy's Wacky New Teaser: Watch

Fall Out Boy put fans in a tizzy today with a mysterious new teaser that appears to be part of their MANIA promotion. It opens with a furry purple creature (similar to the llamas in the band's "Young and Menace" video) pouring purple cereal into a bowl.

The creature soon realizes it can't enjoy the goodies with the mask on. He frustratingly takes it off to reveal a very familiar face beneath. It is none other than—gasp!—Brendon Urie! So could this mean there is a collaboration between Fall Out Boy and the Panic! At the Disco frontman? The teaser's caption ominously states "Woke up on the wrong side of reality," so we just have to be patient and see what the guys have planned.
