Add one more to the Kardashian Klan: Kanye West received a standing ovation from thousands of concertgoers last night after announcing that he and Kim Kardashian are expecting a baby, the New York Daily News reports. He broke the news in song form, singing "Now you having my baby" and urging the crowd to congratulate his "baby mom." Congratulatory tweets soon poured in, including some from the rest of the Kardashians. "Been wanting to shout from the rooftops with joy and now I can!" tweeted sister Kourtney. "Another angel to welcome to our family. Overwhelmed with excitement!" The dad-to-be was making some interesting sartorial choices over the weekend, notes Huffington Post. (More Kanye West stories.)
