Kim Kardashian is pregnant with Kanye West's baby

Kim Kardashian is pregnant with Kanye West's child.

The 'Keeping Up with the Kardashians' star is expecting her first child with her music superstar boyfriend, who revealed the news while on stage at a concert in Atlantic City, New Jersey on Sunday night (30.12.12).

The 'Power' rapper told the crowd to ''stop the music and make noise for my baby mama.''

A spokesperson for the 32-year-old brunette beauty - who is believed to be around 12 weeks pregnant - confirmed her pregnancy, but Kim has remained tight-lipped about her impending bundle of joy.

The rest of the Kardashian clan, however, have tweeted about their excitement for Kim and Kanye.

Kim's sister, Kourtney - who has two children of her own with Scott Disick, Mason, three, and five-month-old Penelope - wrote: ''Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement! (sic)''

Khloe Kardashian Odom added: ''Keeping secrets is hard with so many family members! Especially when you are so freaking excited!!!!! LOVE is everything!!!! (sic)''.

Kim has been dating Kanye, 35, since April 2012 after filing for divorce from estranged husband Kris Humphries.
