The Chainsmokers are blaming their "visual guy" for misspelling Pittsburgh.
The well-intentioned message on their stage backdrop read, "Thank you Pittsburg".
The boys took to Twitter to acknowledge they'll have another shot in "Clevlande".
Haa. We see what you did there, Chainsmokers.
Don't forget- The Chainsmokers are at the Wolstein Center tonight.
The dudes will be our special guest mixers on today's edition of the iHeartRadio Mix At Six.
