Kim Kardashian and Kanye West are expecting their first child.
The rapper announced at a concert in Atlantic City last night that the 32-year-old TV personality is pregnant with his baby.
During the performance at the Revel resort, Kanye sang, "Now you having my baby" to share the good news with the crowd.
The 35-year-old star told the 5,000 concertgoers to "stop the music and make noise for my baby mama," and that it was the "most amazing thing".
Kim was in the audience as he broke the news.
Kim's famous socialite sisters, Khloé and Kourtney, were quick to share their excitement with fans on Twitter.
"Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement! (sic)" Kourtney excitedly posted.
"Keeping secrets is hard with so many family members! Especially when you are so freaking excited!!!!! LOVE is everything!!!! (sic)" Khloé wrote.
The expectant parents themselves have so far refrained from using the social networking site to comment on their news.
The couple will be adding to the ever-growing Kardashian clan, which already includes Kourtney's children with boyfriend Scott Disick, Penelope and Mason.
Khloé and husband Lamar Odom are yet to have kids of their own, but the basketball player was clearly excited about the announcement.
"I'm excited for Kanye and my sister! There's nothing like bringing life into this world! Let's keep Gods blessings coming! (sic)" he tweeted.
Kim and Kanye have been dating since April, with rumours of an engagement rife for months.
