Cardi B Welcomes Baby Girl With Husband Offset

This is the first child for Cardi B and Offset.

Just call her Mama B. 

Rapper Cardi B, whose real name is Belcalis Marlenis Cephus, welcomed daughter Kulture Kiari Cephus Tuesday, she announced on Instagram. 

Pregnancy rumors swirled around the 25-year-old for months before she finally confirmed them in a memorable "Saturday Night Live" performance back in April. 

This is the first child for Cardi B and her husband, Offset, aka Kiari Kendrell Cephus.

Cardi B and Offset wed in a secret ceremony last year.

“There are so many moments that I share with the world and then there are moments that I want to keep for myself! Getting married was one of those moments!" she tweeted on June 25. "Our relationship was so new breaking up and making up and we had a lot of growing up to do but we was so in love we didn’t want to lose each other."
