WATCH: Kanye West Announces Kim Kardashian Pregnancy On Stage

Kim Kardashian is pregnant with Kanye West’s baby. West spilled the beans mid-concert in Atlantic City on Sunday.

“Hold on stop the music for a second,” West said on stage. “Stop the music for a second. Can we make some noise for my baby mama right quick?”

Shortly after West made the announcement the rest of the Kardashian crew offered their congratulations to the couple on Twitter, E! reports.

“Been wanting to shout from the rooftops with joy and now I can!” Kourtney Kardashian tweeted. "Another angel to welcome to our family. Overwhelmed with excitement!"

“Keeping secrets is hard with so many family members!” Khloe Kardashian Odom added. “Especially when you are so freaking excited!!!!! LOVE is everything!!!!

West, 35, and Kim, 32, have been dating since last March, and Kim is approximately 12 weeks pregnant with "Kimye," as the unborn baby has been nicknamed on Twitter. #Kimye has since become a trending topic.

One small snag in the Kanye/Kim relationship is that Kim has yet to finalize her divorce from Brooklyn Nets forward Kris Humphries. Just don’t ask Kanye about Kris, or the man with the happy face announcing pregnancy news will turn red hot, as he did in this video below when a reporter asked Kim about another ex-boyfriend, Reggie Bush, while she and Kanye were out on the town.
