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."
