Beliebers sometimes get a bad rap. They're called annoying, their friends tease them and adults make fun of their enthusiasm. But yesterday we were reminded of just how unbelievably sweet Beliebers can be.

One such Belieber is Miranda who goes by iimaBelieber on Twitter. She collected photos from other Beliebers and posted a super sweet birthday video for Justin Bieber on YouTube.

She tweeted, "obviously justinbieber isnt gunna RT this..i made cupcakes & everything.. & we made this vid."

First of all, those purple cupcakes look delicious. Second of all, Justin did retweet Miranda's video to his over 7 million followers. BTW, can you imagine having that many people leave write 'Happy Birthday' to you on your Facebook wall? LOL.

Check out Miranda's video below featuring Beliebers holding up their birthday messages for Justin along with some nice audio mixing. If you want to leave Justin your own birthday message, write on his birthday wall here.
