Is something going on between Panic! At The Disco frontman Brendon Urie and Fall Out Boy?
FOB posted a video to their Instagram showing a purple llama eating purple cereal that eventually reveals itself to actually be Brendon Urie with the band's new single playing in the background.
So what does this mean?
I mean Urie is friends with the band so he could just be helping to promote their new album...or is it something more?
