In honor of this milestone, “The Ellen DeGeneres Show” was turned into an episode of MTV’s “My Super Sweet Sixteen” as Bieber’s manager Scooter Braun presented his friend and employer with a Fisker Karma, a hybrid sports car. It was a gift from Braun and Usher, who signed Bieber when the singer was 13.

The car has a base price of $96,895, according to Car and Driver. One imagines that Bieber did not receive the basic model.

DeGeneres gave Bieber two slightly less pricey gifts — a sunshade with their faces on it and an Ellen bobblehead.

The teen star, who has been known to give back to his fans, seemed overwhelmed.

Fans of Bieber are trying to give him the gift of a Guinness World Record.

The aptly named Web site HappyBirthdayJustinBieber.com, created by AgencyNet.com, asks fans to send a birthday message to Bieber through Twitter and/or Facebook. They are attempting to set the record for Most Social Media Messages in 24 Hours.

The current record stands at 209, 711. So far, over 152,000 messages have been sent to Bieber.

Bieber showed his gratitude for the gesture on Twitter.

THIS IS AMAZING> the things my fans do. THANK U. A record? Leggo 4 it. SWAG!! happybirthdayjustinbieber.com

To prove once again that he is a megastar who uses his celebrity for good, Bieber has asked fans to donate $18 to charity: water, a nonprofit that provides people in developing nations with safe drinking water. He made the same request last year and raised $47,148.

I promised to always #GIVEBACK so I’m giving up my birthday for clean water for others. join in. thanks - charitywater.org/justinbieber
