Flocks of young teenage girls are sure to be celebrating heartthrob Justin Bieber's birthday today. The Baby singer turned 18 today, a benchmark transition year from childhood to adulthood. And of course, with a milestone birthday comes a gift that's just as extraordinary.

When the now legal singer appeared on the Ellen DeGeneres show, he was presented with a Fisker Karma car by his manager, Scooter. The luxury vehicle's price range lands between $100,000 and $116,00.

You work really, really hard, the manager said according to Celebuzz. I always yell at you-don't get anything flashy. You know, we're not about that. Be humble, be humble and I kind of broke my own rule.

And in the spirit of birthday celebrations, here are five other expensive gifts celebrities have received on their birthdays throughout the years.
