Panic! frontman, famous forehead owner and noted Cookie Monster fan Brendon Urie made a TV cameo last night, appearing on a festive edition of Lip Sync Battle.
Cassadee Pope, the former The Voice contestant, was competing for the ceremonial winner's belt and chose Panic!'s classic 'I Write Sins Not Tragedies' as her big show number.
And you'll never guess who burst through a goddamn door half way through...
It's a fun clip, although it is a bit weird to see Brendon lip syncing to his own song if we're honest.
Cassadee seems delighted though!
But, in the interview with LL Cool J, he makes sure to plug the band's upcoming tour which will be "sweaty and naked" apparently.
Chrissy Teigen has the appropriate reaction to that one...
You are all of us Chrissy.
