The Biebs is no longer a baby. Pop singer and worldwide phenomenon Justin Bieber celebrated his 18th birthday in style Thursday with an appearance on The Ellen Degeneres Show. Thanks to his manager, Bieber will soon fly down the street in a brand new 2012 Fisker Karma, a luxury all-electric car. “That’s for me? That’s for me?” said the singer. Aww, he’s still just a kid.
