Justin Bieber  stewie airport berlin germany hat obey singer

Justin Bieber was snapped at the Tegel airport in Berlin on Sunday, and the 17-year-old pop superstar appears to be growing up before our very eyes!

After recently cutting his hair and losing some of his er, baby face, Bieber has been grabbing his crotch at concerts and he even flipped off the paparazzi the other day. Hmm, is it possible that his "Next 2 U" partner Chris Brown might have a little bit of a bad boy influence on him?
