This is not OK.
Looks like somebody’s heating things up on Twitter!
With a caption that read, #moon, the Biebs tweeted out the pic (above)… and then deleted it!
However, it was already too late — fans all over the social networking site screencapped it and practically EXPLODED!
Bieber’s response after the deletion?
