Cardi B is now a mother of three.

The WAP rapper announced she had welcomed a baby girl in a sweet Instagram post on Thursday, where she posted a slate of photos taken straight from the hospital.

Keeping the caption simple, she wrote, The prettiest lil thing while confirming her newborns birthdate as Sept. 7.

Photos of Cardi cradling her little one were accompanied by images of the baby girl with her two older children, Kulture Kiari, 6, and Wave Set, 2.

Semi-estranged husband Offset was also in the post, tenderly holding the baby in a video.
