Following Friday's release of Justin Bieber's highly anticipated single [1] "What Do You Mean?," Justin debuted the music video for the song on Sunday after his emotional performance [2] at the VMAs. The video is nothing short of sexy, but it also includes another special shout-out [3] to his famous ex Selena Gomez, which most of us might have missed. Thankfully, the Internet caught it, sending social media into a frenzy. On Monday, a Twitter user shared a screenshot of the video that clearly shows Selena's name spray-painted on a wall.
