Move over Kate Middleton, Kim Kardashian and Kanye West have confirmed this morning that they are expecting their first child. The pregnancy was revealed by Kanye during a concert in Atlantic City, USA on Sunday night.  Kim was sat in the audience and was reported by witnesses to have seemed as shocked as the other concert-goers at Kanye’s surprise announcement. West, according to a flurry of audience tweets, shouted “stop the music” before beaming excitedly and announcing “make some noise for my baby mama right here.” Although Kim is still married to her estranged second husband Kris Humphries, the couple have been dating for eight months.  Sources close to the couple told Arabstoday that Kim is thought to have conceived 12 weeks ago. Sister Kourtney took to twitter to comment: “Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement!” But no doubt Kim’s other sister Khloe, who has been trying for a baby with basketball superstar beau Lamar Odom for over a year, will be less pleased with the revelation. Khloe wrote on her twitter page: “Keeping secrets is hard with so many family members,” while Lamar chimed in with: “There’s nothing like bringing life into this world! Let’s keep God’s blessings coming.
