During EXO's stage at '2016 MAMA', Chen's pants tore while performing "Transformer". He fixes it expertly by taking his jacket off and tying it around his waist. He performs professionally with the temporary fix, but during "Monster" when all members have to go down onto the floor, he gets a little flustered and smiles, a little embarrassed as he covers himself up with his jacket.
Check out the video above! He can be seen at 1:38 taking his jacket off and tying it around his waist, and then his cute smile can be spotted at 9:46.
