UNDATED (CNN) -- Rapper Kanye West and his girlfriend, Kim Kardashian, are having a baby.
The two have been dating for about eight months. They've denied pregnancy rumors in the past, but a spokesman for Kardashian confirms the news to CNN.
West made the announcement at a Sunday show in Atlantic City, New Jersey.
The Monday morning tweets spread fast from Kardashian family members, including Kim's mother and sisters.
Kim Kardashian is still legally married to NBA player Kris Humpries, although she filed for divorce in October 2011, 72 days after the two were wed.
