NEW YORK • The baby girl's name is Kulture Kiari Cephus.
On Wednesday, Cardi B, 25, who has quickly risen to become one of the most prominent women in hip-hop, announced that she has become a mother.
The rapper broke the news on Instagram where she posted a picture of herself pregnant, nude and tattooed in a room full of flowers.
She said her daughter was born on Tuesday. The father is rapper Offset, one-third of the hard-living Atlanta hip-hop trio Migos. He has three other children from previous relationships.
The baby's name clearly reflects her father, who was born as Kiari Kendrell Cephus. Migos has albums called Culture and Culture II.
Cardi B has become one of the biggest new stars since the success last year of her song Bodak Yellow, which touches on her former life making ends meet as a stripper.
She initially kept her pregnancy under wraps before showing off her baby bump in an April television performance on Saturday Night Live.
She went ahead afterwards with a performance at Coachella, the leading United States music festival, where she briefly twerked on stage.
She recently confirmed reports that she secretly married Offset.
Cardi B - whose debut album is titled Invasion Of Privacy - voiced anger at the news coming out, but said "at least ya can stop saying I had a baby out of wedlock".
