Cardi B shared the news care of a naked pregnancy Instagram photo, in which she also shared her baby's name: Kulture Kiari Cephus.
According to marie claire US, Cephus is the last name of Offset, whose real name is Kiari Kendrell Cephus.
We bet Kris Jenner is livid she didn't think of this one first...
Baby Kulture is Cardi B's first child and the fourth for Offset, who has three children from previous relationships. The couple secretly married in September, but didn't make the news public until last month.
Just a few weeks ago, Cardi B celebrated her impending arrival with a 'Bronx-Fairytale' themed baby shower.
Congratulations to the couple!
