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 newborn’s 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.

Cardi’s Instagram seemed to suggest she was on good terms with the Migos rapper. She filed for divorce at the end of July.

In August, Cardi’s fans experienced a whirlwind of emotions when she announced she was expecting on the same day the divorce made news.

“With every ending comes a new beginning!” Cardi wrote on Instagram. “I am so grateful to have shared this season with you, you have brought me more love, more life and most of all renewed my power!”
