Justin Bieber's hot — we mean, REALLY hot!
Not worries though!
Even though the AC wasn't available to cool down the seksi teen heart throb during his Korea show on his Believe Tour, the sweetheart sang that everything would Be Alright on Sunday.
What a trooper!!!!
However, we are surprised he didn't take the heat as an opportunity to strip! LOLz!
Ch-ch-check out the super steamy performance…AFTER THE JUMP!!
