Nick Jonas celebrates 21st birthday at XS Nightclub and Botero inside Wynn Las Vegas 

I love kevin the most personality wise. Hes so relaxed and funny (he was hilarious in his reality show). He actually looks happy too.

that true nick n olivia aren't right together Nick n priyanka look mad for each other even if she look older than him but she really loves him not his fame that's why nick Jonas proposed priyanka for marriage

lol the fact olivia didn't know whether or not to kiss him, it was so awkward

See how Olivia is just always I front of the cameras and we all know why lmfao. 😂

A lot of random people invited but where´s Demi? I mean, she´s a great friend of Nick.

Time has flown so fast, one second it was 2007 and they were singing When you look me in the eyes, then I blinked... :)

truly a gentleman, nick reminds me of myself he's really shy so he's really awkward in these situations

he's an introvert so he probably doesn't completely enjoy all of the attention and people --- that's probs why the actually party was only 20 ppl then they went to the club

I'm already crying, from 2006 to now, love ya Nick!

I remember when he was 15 now he's 21 omg I'm crying

Nick! You are so handsome!

This video only convinces me more of the fact that Nick and Olivia aren't right together and she's just using him for the fame

That boy knows he's fine!

And i thought few years back i would marry one of them. How could I compete with those beautiful ladies? And they all look real happy too. Though I miss my boys, I'm so proud of what they've become.

LOLOLOL this reminds me of that video about how smartphones have taken over the lives of evryone these days, like that scene in the video where its the persons birthday and everyones on their phone LOL

what is the song of the minute 3:30?

You can hear Nick whisper "Love you" ay 1:06 :D

Happy Birthday Nick Jonas!!!!❤☺🙂

They look so happy!

I love Kevin and Dani together

Diooooosss que papiiiiii, que homnreeeeee, que porteeeeeeee de elegancia dios te amoooo NICKKKKKK♥

The moment I realized Kevin and Joe were there

He looks so happy.

Dang i would like to have a big birthday party like that for my birthday in the future with no singing at all.

click the title to see the full title

hes ridiculously good loooking

Nick looks so happy :)

i don't think nick and olivia are gonna last long..not that i don't like her or want to see him happy i just don't see it working out

I love Dani for Kev , I like Blanda for Joe but I totally dislike Olivia for Nick!!! She just seems like she always want to call atention , she's in my opinion not what Nick deserves.

1:55 Kevin rubbing Dani's belly

WHERE'S DEMI?!?!?!?

blanda was more excited than nick sdkjhdskj lol shes so sweet

That kiss at 1:04 was so awkward. I love them and they're adorable but that made me uncomfortable...

Awww, Kanielle! Nolivia is cute

Well he looks happy.

Relaxed dude it's your birthday:)

The nick and olivia kissed gosh I feel crazy

Im sorry but im i the only one that thinks he looks miserable with olivia

olivias theme song should be video girl 😳

Love you Jobros, forever and always!!!

so fancy

Nick really needs to grow out his hair! ^_^

Happy birthday Nick Jonas I am in love with you I let you now

She seems alright in her candid interviews. I just feel she seems like a figurine when she poses. Did you notice that they all harmonized at the end of Happy birthday?

can you imagine them gettong married, all of them

those were the days....

do they still have purity rings? :O

Olivia looks like "I'm really boring, i don't care, well i'm going to see all the post on my cellphone" They look beautiful sometimes, but sometimes she is in another world, so i don't know. And Nick you really need be more relax, it was your birthday, so man just take a breath and let you go wild. DUDE!!

Happy Birthday 21 Nick Jonas

she was crowned Miss Universe 2012

awww i love you nick

Everyone should leave Olivia and Nicholas alone. They love each other< they loive together so... thats not of your business to discuss her.

LOL I happened to read your comment because of someone who replied to mine. Aren't purity rings til marriage though? lol they seem too gorgeous of a couple to hold it haha

I want a birthday like this :333 Love you babe 3

TRUE! HAHAHAHHA

My perfect man!!!

The dude's so pretentious...

lol

Ohhhhh nyc

KEVIN \*O*/ DANIELLE \*O*/ JOE \*O*/ BLANDA \*O*/ NICK \*O*/ no me falto nadien mas?? creo que vi a alguien de morado pero que mas da xD

Aww

How cute!

Who is watching this in March 2016? Is his girlfriend still with him? ( no offense just asking)😗😙

I'm not friend of Nick I'm friend of Priyanka if he not geting marry priyanka so many boys are there who Love priyanka

1:05

Only priyanka 🥺❤️

why the jonas girl are dani, blanda and Olivia :/ the jonas girl should be selena miley demi or dani miley demi xD

♡

Oh Nick even in our own birthday party you looks uncomfortable. Man enjoy yourself a little bit sometimes, this isn't crime! You only live once! I think he takes the things so much serious with afraid to seem ridiculous.

blanda se ve muy feliz con joe

The girl in purple is a beauty pageant or something? I think is the only excuse to that behavior.

no honey they don't.

Why they didn't invited Demi 😐

Kevin and selena???? never............ Dani is perfect for him. Demi and Joe are too alike to be together. Blanda is older and seems to balance him. Demi also has a lot of growing up to do. Miley is not right for Nick. They were not right when they were 14 and aren't now. Nick was way more in love with Delta than Miley. That is how life is. You grow up and find out love grows stronger with age and sex in relationships. Also, she is not classy enough for him. He likes girls he take home.

Quien iba a desir que se casaría con Priyanka 😏

I should have been there

:') my baby...

There is just something I don't like about Blanda, I don't know what but I don't like her at all...

Nick is hot but weird

Man, he looks like such a pretentious dude.

okey :)

Nick ur lucky man u get nice wife

I luveuunike

Carpet paparazzi etc for his birthday.... okay....

When I saw him kiss that girl, I was like WTF.

Like ...

Pinche Olivia :'(

Olivia was so fame hungry. And then he goes and marries a camera hog.

Really,clubbing and drinking? This really makes you happy? What about your relationship with the Lord? I guess sin is indeed fun for a season.

I personally think nick Jonas and Olivia don't really deserve to last long because their to sacrifice their relationship being together and I don't see him being with her for to longand I personally don't think that nick Jonas really doesn't derisive to last that long with his wife priyanka chopra jonas because vi know it's not going to last long the divorce papers will come soon
