Justin Bieber celebrated turning 18 with Ellen today and even though it was his birthday, he was also in the giving mood.

Bieber tweeted that he had a big news to share before the show.  When Ellen asked about the news he said,

"My big announcement is that on March 26th, my first single is coming out and it's called 'Boyfriend'"

Shortly after Bieber and Ellen talked about the new song, he got a surprise of his own.  His manager Scooter Braun surprised him with a birthday gift.

After listing off Bieber's charitable ways, including meeting with a Make-a-Wish kid after every show for 86 dates during his tour, Braun showed off Bieber's new car: a new (and hard-to-get) Fisker Karma.

Ellen put her own spin on her gift to Justin; sun shade with a heart over DeGeneres and Bieber, as well as a bobble-head.
