Cardi B confirmed that she and the hip-hop artist Offset secretly married in September, despite months of publicly insisting they were just engaged.

On Monday, TMZ published a marriage certificate that indicated the two — whose real names are Belcalis Almanzar and Kiari Kendrell Cephus respectively — married in a September 20 ceremony in Atlanta.

Cardi B came clean, saying it was a private ceremony with just the two of them and one of her cousins.

“There are many moments that I share with the world and then there are moments that I want to keep for myself,” Cardi B wrote in a screenshot of the iPhone Notes app posted to Twitter. “Getting married was one of those moments.”

Offset apparently proposed to Cardi B during a concert in October, but some details surprised fans. She kept her pregnancy a secret until April, and Offset called her “my wife” at the BET Awards on Sunday.

The two were married the whole time.

“I appreciate my husband so much for still wanting for me to have that special moment that every girl dreams of when he got down on one knee and put a ring on my finger,” Cardi B wrote.

She said the event was low-key. She didn’t wear a wedding dress, get special makeup, or make other elaborate arrangements.

“I said I do, with no dress, no make up and no ring!” she wrote.

And it was all a secret.

“We had a lot of growing up to do but we was so in love we just didn’t want to lose each other,” Cardi B wrote. “One morning in September we woke up and decided to get married.”

The singer also lashed out to people who gossiped about her apparently having a child out of wedlock.

“Well now since you lil nosey f—s know at least ya con stop saying I had a baby out of wedlock,” she wrote.
