Photo: Justin Bieber with his zip down… again

Dear Justin Bieber, do up your trousers!

This isn’t the first time J-Biebs has been caught with his zip down. The teen singer looked very smart in his white tux at the Grammys, however the teen sensation suffered a terrible wardrobe malfunction.

Then, the same thing happened again at the Brit Awards.

This time it happened in front of a huge audience of fans, at a gig in Liverpool.

Coming on stage with it already down, Bieber apparently spent most of the show with his hand strategically covered his crotch.
