[louizoulaleisou]

tomorow is his birthday!!!!

[taylorswift091196]

Happy birthday Justin! 

[SuckasItsMe]

@cloudemcfester I wish other people could see your logic. I prefer rock and metalcore to pop, but I also see the good he does for other people. If people would look at it from your point of view there wouldn't be as many arguments.

[becafraguas]

2 DIAS ♥ meu divÕ lindoooooooo!

[TheTayw97]

That was surprisingly BAD.

[Ruben1980]

come on you can do better

[cloudemcfester]

its funny, cuz i dislike 90% of Justins music, and most people would call me a hater, because i look like youre average rocker who hates all pop and stuff. But the reason i dislike justin, is cuz I simply dont like his songs, i think some of them lack depth or stuff like that. But i always see this guy doing so much good stuff that it is impressing, even though he isnt smart or stuff like that, he is a great guy. And this is my christian part talking right now and it says, Justin ROCKS

[BieberChick687]

The first time I saw this on Tv, I died and went to heaven.

[courtneyrosexoxo1]

My mom said thanks. (It's her birthday today.)

[zooropah82]

Justin bieber can suck my balls

[Sarannario]

Pls today is my birthday follow me on twitter @sarannario

[xxxMINECRAFTxHELPxxx]

you suck ba11s!

[xxxMINECRAFTxHELPxxx]

you suck balls!

[6jbnatu]

OMG!!!!! and today is my Birthday!!! thank you Justin Bieber!! <3

[werpomapet1987]

OH my! Jusstin Bieber Put his big C0CK in his GF now here at JustinBest.way.to 0MG! This is so Crazy!

[JustinDBieberMyHero]

I have a few things to say... 1. Justin is amazing! He helps others out. 2. You most likely dont know him. You dont need to like his music, but at least RESPECT HIM! 3. How can you dislike this when it's for a good cause?

[edwinljb]

MGGGGGGGG JUSTIN IS THE BESSTTT :d

[marigold1525]

happy birthday to me <3

[devotedlittlemonster]

His voice is so weak...it suited him better when he was younger. I'm not saying that he isn't a good singer, it's just that his voice/singing style is reaching its expiration date.

[BieberFevergirl1193]

It's funny haters, cuz your girlfriends want him more than you..

[benediktea96]

haha, aww. I'm watching this on my birthday

[Dream4Lifex3]

I have this on repeat today for my birthday... lol :)

[Muhullapino]

hehe its my birthday today my heart just melted when he sang this

[TheElementkid300]

Justin bieber sended this video to me when it was my birthday

[TheElementkid300]

The real justin bieber sended this video to me when it was my birthday!!

[JustinBieberFan20307]

aww today's my birthday too *-*

[MyDolphin07]

???

[nexttojb]

my friends played this and suprised me with a birthday party :D

[DeathhimselfTHS]

all you Bieber haters (specifically of the male gender)...he's singing for a good cause, he has a good voice, and you're jealous because he has all the girls.

[andresoacuna]

@DeathhimselfTHS Yeah.. All the 8 year old little girls.

[sonialambeck]

@DeathhimselfTHS he has all the girls ? not me...

[MsRegilio]

@sonialambeck hahaha yeah right 

[DeathhimselfTHS]

@sonialambeck can you not allow a general comment? the average American girl of this day has Bieber Fever, you can't deny that. So I generalized; get over it.

[11lululuv]

lol he would fix his hair at a moment like this :P (0:11)

[bieberfever1561]

I bet every belieber listens to this on their birthday I know I do

[MrsNickj00777]

Haha i found this 4 days before my bday :)

[znvidmar]

am???? wtf??? he likes boys?

[ProudOfGreekBelieber]

Today I Have Birthday :'}

[MuzicXLoveR]

WAAAAAAAHH today's my 15th birthday, this REALLY made my birthday! First it didnt really feel like its my birthday, but now it soooo does! I LOVE HIM SOOOSOOOOSOOO MUCH! I wish one day he'll notice, tweet and follow me... i would be the happiest girl IN THE WORLD! My biggest wish is to meet him, so i could tell him how much i LOVEEEE him! #NEVERSAYNEVER #PROUDBELIEBER #HATERSGONNAHATEBUTFCKYAAAALL

[AriaTheOfficial]

This is for me, because my birthday is tomorrow.

[DeathhimselfTHS]

[fatcat01able]

0:23 his pants are sagging and his shirt is put in his stripped red and black boxers... is this really the style of our generation..

[girlyoudontknow12341]

How does this help cancer?

[DJKykieD]

Today is my bday! Valentines Day!!!!! :D last yr my sis sent this to me on my bday and i almost cried!

[hariupad007]

I have just found out why I hate Justin bieber. I looked this vid up because I wanted to c if he did it here. He does too many pitch bends and puts too many ooo's and ooohh's into his songs! And his voice is strained a lot and is to high for his age! Many people will agree! (I do not mean to offend anyone)

[hejella1]

00.35 ♥

[idan111]

What a cruel way to end their lives.

[irandomnessnation]

AHHHHH I love this so much! ANd its my B-Day! so happy right now

[RihannaLuver3335]

Whoever's leaving awful comments shut up. This is for cancer and he's sweet to do this. You don't have to love him to be proud of him for doing this. Seriously, if you had cancer you would be happy for anyone to care enough.

[SuperClipsVEVO]

FUCK U JB !

[skullskater816]

U suck

[Thanasorn100]

FUCK!!! JB

[xxlisaatjexx]

IT'S MY BIRTHDAY :)
