Cardi B has confirmed she got married in secret nine months ago.
The rapper revealed she tied the knot on the same day her boyfriend Offset, from rap trio Migos, proposed to her.
The couple are expecting their first child this summer.
Gossip site TMZ was first to report the marriage, posting a copy of the wedding certificate on Monday.
"One morning in September, we woke up and decided to get married, said Cardi.
"We found someone to marry us, and she did, just the two of us and my cousin. I said I do, with no dress no makeup and no ring!"
Bizarrely, one month later, Offset proposed to Cardi on stage during a concert in Philadelphia.
Secret weddings
Cardi B and Offset aren't the only artists to keep their marriage secret from fans. Here are some of the others who managed to keep their vows private.
Penelope Cruz and Javier Bardem - Although they started dating in 2007, the actors never confirmed their relationship - "He's a friend and the best actor in the world," was Cruz's standard response to questions about Bardem. They married in a private ceremony in the Bahamas in 2010, a spokesperson later confirmed.
Beyonce and Jay-Z - Rumours had circulated for years that the musicians were dating, but fans were astonished when they filed a signed marriage license in New York in April 2008. Six months later, Beyonce confirmed the wedding to fans.
Janet Jackson and Rene Elizondo - News of Jackson's second marriage only came to light when she divorced video director Rene Elizondo in 2000. The couple had, however, worked together for 15 years. Elizondo had co-writing credits on dozens of her songs - and it was his hands that covered her breasts on an infamous Rolling Stone cover.
Janeane Garafalo and Rob Cohen - Incredibly, this comedy power couple were married for 20 years without knowing it. Garafalo (The West Wing, The Truth About Cats and Dogs) drunkenly tied the knot with Big Bang Theory producer Cohen at a drive-through chapel in Las Vegas in the 1990s. They only realised the ceremony was legitimate in 2012 when Cohen started making plans to marry his new fiancee and his lawyers dug out the marriage certificate. The couple immediately filed for divorce.
Margot Robbie and Tom Ackerley - The couple never announced their engagement, and married in secret in Australia two years ago. Robbie eventually confirmed the union in an Instagram post showing off her wedding ring.
Cardi B, whose real name is Belcalis Almanzar, rose to fame last year with the song Bodak Yellow while her current single, I Like It, is a contender for 2018's song of the summer.
A former gang member and stripper from the Bronx, she took a modern route into music, establishing her name via reality TV and social media.
She and Offset were recently photographed together for the cover of Rolling Stone magazine. In the accompanying interview, Cardi said motherhood would not affect her career, reports BBC.
