Looks like "Keeping Up with the Kardashians" is getting a new cast member. Kanye West announced during a concert in Atlantic City Sunday that he and girlfriend Kim Kardashian are expecting a baby.

He addressed the crowd of 5,000 with the news in song form: "Now you having my baby."

Reps for West and Kardashian have yet to respond to the news.

Kardashian was briefly married to NBA baller Kris Humphries, while West previously dated model Amber Rose. The couple finally went public with their relationship in March.
