On Sunday night, Kanye West “announced” that he and Kim Kardashian are expecting a child together when he told the crowd at his Atlantic City concert to “Stop the music and make some noise for my baby mama,” according to a fan on Twitter who was at the show, and then reportedly pointed to his girlfriend in the audience. Although Kim – who is still married to her husband of 72 days, Kris Humphries – has yet to say anything to her nearly 17 million fans on Twitter, her rep did confirm that the reality star is pregnant. This will be the first child for both Kim, 32, and West, 35, who began dating in the spring of 2012. Of course, the moment West, 35, made the big announcement, Kardashian’s attention-loving family took to Twitter to share their well wishes and blessings to KimYe’s unborn “kash kow.” Youngest sister Khloe Kardashian, who has struggled to get pregnant with husband Lamar Odom, wrote, “Keeping secrets is hard with so many family members! Especially when you are so freaking excited!!!!! LOVE is everything!!!!” Oldest sister Kourtney Kardashian, who just gave birth to her second child in July, also gushed, “Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement!” Kris Jenner, the matriarch and manager of the Kardashian-Jenner clan, added, “Oh BABY BABY BABY!!,” while her 17-year-old model-reality star daughter with Bruce Jenner, Kendall, tweeted, “whos excited about the KIMYE babbyyy?! :D weeee.” As of press time, Kim’s brother Rob Kardashian and stepbrothers Brody and Brandon Jenner had yet to share their thoughts on their new niece or nephew.
