Calling all Beliebers! In honor of Justin Bieber's 19th birthday (March 1), PopCrush and Island Records have partnered up for a contest where we will be giving away an acoustic guitar, like the one pictured above, signed by The Biebs himself.

Let the shrieking begin, as this is one prize you want to win, since it bears Justin Bieber's John Hancock. How awesome is it that you have the chance to win a killer gift from The Biebs via a contest launching on his birthday?

The contest runs until 11:59PM ET on Sunday, March 31. To enter, all you have to do is follow @PopCrush and @IslandRecords on Twitter and retweet the contest announcement by clicking the blue button below. It's a smart move to follow us and them on Twitter anyway, since you can keep up on all the news about The Biebs and tons of other pop acts.

See how easy it is?

The fine print contest rules are here, so be sure and read it. And then RT, so you can have a chance to win a guitar signed by The Biebs, which you can play, make beautiful music with or mount on the wall with other items in your Bieber collection.

The Biebs' latest chart-topper, 'Believe Acoustic,' is out now. Grab it here.

Good luck, Beliebers!
