Justin Bieber Sings About Passing Out in Korea [VIDEO]

North American treasure Justin Bieber can't stand the heat.

The Biebs is on tour on the other side of the world. At his recent (Oct. 10) show in Korea, the teen improvised the lyrics to his song 'Be Alright' since he was dealing with some serious heat in the venue and was thisclose to fainting! Oh no!

At the 1:30 mark of this live video, a visibly perspiring Biebs changed the lyrics after wiping himself with a towel, singing, "I wish I had AC / It's getting real hot up here / I think I'm gonna pass out any second / But everything's gonna be alright."

Oh that Biebs! He can be cute when he wants to.
