He's the one of the most famous celebrities on the planet, and now he can finally vote.

March 1 marks Justin Bieber's 18th birthday. So yes, Bieber is of age. However, the pop star has nothing lavish planned for his big day.

Bieber, who currently dates actress Selena Gomez, recently stated details of his low-key affair.

My birthday, I'm going to hang out with my friends and family, have a little get-together; nothing too crazy, said the Canadian singer.

Instead of looking for gifts, Bieber wants people to give to his charity.

On Twitter, Bieber posted: i want to use my bday to help others. if u want please donate $18 to @charitywater on my 18th bday!

Bieber already received a rather cool gift. On a Wednesday appearance on The Ellen DeGeneres Show, Bieber's manager Scooter Braun presented him with a luxury 2012 Fisker Karma sportscar with a solar-panelled roof.

A Fisker Karma can cost up to $116,000, so Braun really hooked Bieber up with an expensive birthday gift. Braun advises Bieber to be humble, but he felt his star client deserved to be rewarded for his hard work.

That's for me?! That's crazy! Bieber exclaimed.

Bieber is no stranger to automobiles. He already has a Ferrari and a Cadillac Batmobile in his collection.

There is still no word on what Gomez got him for turning the big one-eight.

Here's the video of Biebs on Ellen:
