Cardi B and her supposed fiancé Offset, who are expecting a child together, are actually already husband and wife, according to a marriage certificate obtained by TMZ.

The certificate was filed under their legal names, Belcalis Marlenis Almanzar and Kiari Kendrell Cephus, on Sept. 20, 2017, in Fulton County, Georgia, where they both currently reside.

Cardi B confirmed that they’d secretly wed in a note released Monday on Instagram that talks about “moments that I want to keep for myself!” She explains that the two woke up one morning and decided to tie the knot in private with just her cousin as a witness.
