Justin Bieber turns 18-years-old today -- and he's driving into adulthood in an awesome (and very expensive!) new car!
The birthday boy filmed his guest appearance for today's episode of "The Ellen DeGeneres Show" the other day ... where manager Scooter Braun appeared with a very special surprise gift.
So what do you get the guy who could probably buy anything he wanted for himself: A Fisker Karma!
The super-exclusive, luxury hybrid car retails for around $100,000 ... and that's just the base price.
While on the show, Justin also had a present for his fans -- revealing he'll have a single out called "Boyfriend" on March 26.
