Report: Cardi B, Offset secretly married in September

June 25 (UPI) -- Celebrity couple Cardi B and Offset reportedly married in secret in September.

TMZ said Monday the pregnant 25-year-old rapper tied the knot with Offset prior to their very public engagement last year.

A marriage certificate shows Cardi B and Offset were married by a minister Sept. 20 in Fulton County, Ga. The certificate uses the couple's legal names, Kiari Kendrell Cephus and Belcalis Marlenis Almanzar.

Offset, a member of the rap group Migos, referred to Cardi B as his "wife" during an acceptance speech Sunday at the 2018 BET Awards.

"Thank God. I thank my wife. You should thank yours," the 26-year-old rapper said, according to People.

Cardi B and Offset got engaged during a concert in Philadelphia in October. Cardi B announced her pregnancy in April, and confirmed in an interview with The Howard Stern Show the next month she's expecting a daughter.

"I'm having a girl," she told host Howard Stern.
