Cardi B, real name Belcalis Marlenis Almanzar, married the Migos singer Offset, real name Kiari Cepheus, in a secret ceremony in September 2017.

The 27-year-old singer made the filing on Tuesday in Atlanta in Georgia - near their marital home.

Tuesday's filing states that the divorce is being contested by Offset, 28, with whom the rapper has a daughter Kulture.

Cardi B is asking for "primary physical custody" of their daughter while asking that Offset contributes to her "support and maintenance".

It adds that the couple are living in a "bona fide state of separation" and that their marriage is "irretrievably broken".

There are "no prospects for reconciliation", according to the filing.
