Justin Bieber Is Petty

Justin Bieber is 21 with the maturity of a 12-year-old. Following news that Selena Gomez and One Direction member Niall Horman were making out at Jenna Dewan’s 35th birthday party in LA on Friday, Bieber posted a “throwback” photo of him and Gomez holding hands.

Because only children think this would bother their ex’s boyfriends. I’m sure Justin Bieber is exactly what Niall is thinking about while he rams his tongue down Selena’s throat.
