Justin Bieber's Fisker Karma

Justin Bieber's Fisker Karma, Justin Bieber has got so much swag, he's now giving it away -- literally. The 18-year-old pop star has gifted friend Sean Kingston with his chrome-plated Fisker Karma hybrid (which itself was a birthday present to Biebs, from manager Scooter Braun). The car cost a reported $100,000.

"When you're best friends with one of the biggest artists in the world, you get all different types of gifts. And this is one of them," Kingston told TMZ. He also said that Bieber planned on getting the new Fisker Karma when it came out.

The tradition of giving cars to friends isn't anything new in Hollywood, of course. Kim Kardashian recently bequeathed boyfriend Kanye West with a reported $750,000 Lamborghini for his 35th birthday, while Jennifer Lopez dropped off a customized Dodge Ram pickup truck for beau Casper Smart's 25th birthday.
