The moon shot wasn't up for long, but still long enough to necessitate a comment from Bieber's manager Scooter Braun.

"[A]s a prankster u have to respect another good prank. only makes sense. #crackdealer," Braun tweeted following his client's ass-play.

USA Today, however, suggests the cheeky candid was less of a "good prank," and more of a "regular PR move" to attract new followers ahead of Bieber's upcoming remix album, Believe Acoustic.

Then again, he may have been helping his mom promote her upcoming anti-abortion film by showing horny youngsters God's loophole.
