Hollywood rappers Cardi B and Offset welcomed a baby girl.
The duo, who got secretly married nine months ago, took to Instagram to announce the arrival of their daughter.
The rapper shared a pic of her posing nude and captioned it: 'Kulture Kiari Cephus (which we presume is the baby's name). 07/10/18.'
'No better feeling,' she added. Cardi is yet to share an image of her daughter.
Followers of the rapper felt that Cardi was copying Beyonce's way of announcing the birth of her twins.
In June, the duo starred on the cover of Rolling Stone before their biggest collaboration: a baby girl.
Congratulations Cardi B and Offset on the new addition to the family.
