The crowd roared. And so did people on the Internet.

The news instantly went viral on Twitter and Facebook, with thousands posting and commenting on the expecting couple.

Most of the Kardashian clan also tweeted about the news, including Kim's sisters and mother. Kourtney Kardashian wrote: "Another angel to welcome to our family. Overwhelmed with excitement!"

West, 35, also told concertgoers to congratulate his "baby mom" and that this was the "most amazing thing."

Representatives for West and Kardashian, 32, didn't immediately respond to emails about the pregnancy. Sources told TMZ that Kardashian is 12 weeks pregnant and that she had no idea West would be announcing the news, though she didn't mind that he did.

The rapper and reality TV star went public in March.

Kardashian married NBA player Kris Humphries in August 2011 and their divorce is not finalized.

West's Sunday night show was his third consecutive performance at Revel. He took the stage for nearly two hours, performing hits like "Good Life," "Jesus Walks" and "Clique" in an all-white ensemble with two band mates.

Kim FINALLY got what she wanted --> a BLACK MAN's SEED planted in her polluted womb & a lil "claim" to BLACK CULTURE. She actually accomplished something that didnt involve getting f**ked & p!ssed on & having it recorded. Kanye wants what Jay-Z has --> a beautiful woman (Beyonce). Kanye may even secretly WANT Beyonce!! <--- He sure az hell announced that Kim "is his Beyonce" when he & Kim first started seeing each other, and God KNOWS Kim is NOTHING like Beyonce. Kim is not talented, she's not genuine, she's not married & she's not beautiful. 95% of Kim's FACE is wiped off every night & reapplied the next day. Kim is still in the sham of a marriage with Kris Humphries. Kim got married, separated, involved with AND pregnant by another all within ONE YEAR. Kim PLANNED this pregnancy. And Kim's mom KRIS JENNER probably advised Kim to "get pregnant by Kanye & have his baby YOU WILL GET PAIDDDDD". KIM is too self-absorbed, self-centered, obsessed with TV cameras, photo shoots, MONEY & ATTENTION to have a baby. She doesnt DESERVE to have a baby - Kim is fulla sh***t & Kanye is a STUPID N***GGA -- my GOD -- KANYE IS A STUPID N***GGA - he is a LOUDMOUTH, a CRYBABY, he throws TANTRUMS & he wants to boycott the Grammy's because he didn't win an award. The WORLD is watching while Kanye & Kim produce BASTARD KIDS outta wedlock, after only being together for 8 months. And what's worse is there are actually people APPLAUDING HER!!!! Isn't it a TAD BIT too soon to be doing what Kim & Kanye are doing???

Like i could give a ****.

Is Mrs. Humphries sure of the paternity of this baby? What are the child's chances of making it to delivery? What are the chances Mr West will be there to see the baby's first steps? To see him graduate college, I mean high school, I mean pre-school?

[Kerahdah]

Wow, what a ROLE models they are for young people struggling to deal with relationships!!!

[mandiegracetaylor]

I am amazed - as an American - that anyone used the word adultress - married - about these two - it's amazing - I didn't think it could occur anymore. But Kanye will now get what he didn't get at the music awards and his fans - a video camera constantly zooming onto his lit up face - a microphone on every talk and reality show there is - and more attention than he has sat somewhere and dreamed of - simply because he scored this babe known as Kim. She and her child will be crushed by photographers - surrounded by body guards and will be caused to become even more dysfunctional than they already are -

Sorry, but gotta say it. What a STUUUUPID *****! When will women learn?

1. She's STILL married to someone else = *****, ADULTRESS. Kenye is a male ***** adulterer. Sex with a married woman.

2. She hasn't even been dating him that long, let alone known him that long.

3. She screwed him without a CONDOM? STUPID *****!!!!!! He put you in bed with everyone he's been with and everyone his partners have been with. And you put him in bed with everyone you've been with and everyone your partners have been with. STUPID!

4. Another stupid woman having a baby with a man she isn't married to and hardly knows. When will women LEARN? Stop being STUPID. It's called PREVENTION! Condoms, birth control pills or Just Say NO!

I give it 2 years, if that and I'm being generous. She thinks he knocks her socks off in bed (that's really what it's all about.) My darling Kim, that only lasts for a season, hon. I can tell you right now he will NOT stick around. GUARANTEED he'll find some reason to flit off into the sunset like they always do.

If there is one thing black men are really, really good at is turning their backs on their own children. They do it incessantly. Stupid, stupid, woman. Oh and just for reference, I'm a black woman who knows all too well the soul of the black man. Been there, done that.

GUARANTEED they will be in court before 2 years have gone by. Watch and see what I say. They'll be calling each other names and throwing stuff at each other. She sure is one stupid ass woman.

BET he never marries her. Why should he? He got what he wanted - some strange PSY. And guess what Kim, YOU AIN'T THE LAST WOMAN HE WILL BE WITH you stupid girl! Open a book instead of your legs!

Without a condom, Kim? Really? What the HELL were you thinking??? Aren't you too old to be making these kinds of mistakes? Good Grief!!!

It wasn't a mistake. Just another source of revenue.

These people, the whole bunch, are disgusting !! Everything they do, is for media attention - why do people even watch these horrible people ?? They have no morals whatsoever and the last straw, for me, was that ridiculous display of love and affection - NOT - I'm talking about the "Wedding Sham of the Century" ... What a joke !! I mean come on - everything was paid for/donated and ALL THE GIFTS - should of been sent back - but instead SHE keeps them - what a PIG !! They deserve each other - one conceited pig deserves another !!

A few years ago, West proved himself to be a conceited, immature piece of trash when he interrupted Taylor Swift at the music awards to cry that he was the one who should have gotten the award. What he should have gotten was a beatdown from security. Kim, if she is even able (God knows she's screwed up too), will have TWO children to raise - that is if West sticks around long enough.

[mandiegracetaylor]

He's crying all the way to the bank now - some magazine is going to give him and Kimmy five million dollars for a three hour photoshoot and the money will go to their favorite charity - themselves.

[themooniac]
