They announced their engagement in October last year.

Cardi B and Offset have reportedly secretly gotten married....almost a year ago. The couple, who are expecting their first child, are said to have exchanged vows in September last year. Speculation that the two may have already said 'I do' began after Offset thanked Cardi B at the BET Awards on Sunday night - and called her his wife. Accepting the Best Group award, Offset took the mic from fellow Migos star Quavo and and said: "I thank God, I thank my wife." https://twitter.com/beyoncecardib/status/1011223839202824192 TMZ managed to find a marriage license for the couple, which is from Fulton County in Georgia...and was filed last year. To be more precise, September 20, 2017. The certificate is filed in Cardi B and Offset's given names, Belcalis Almanzar and Kiari Kendrell Cephus. So, basically, this means that the pair would have been married before that date - as the certificate wouldn't have been filed until then. Offset "proposed" to Cardi B in a very, very public way in late October last year. https://www.instagram.com/p/Baxq1LRDVPK/?utm_source=ig_embed Cardi B announced that she was pregnant with her first child in April this year. Having been plagued by rumours, Cardi chose to share the news with the world by pulling a Beyoncé and unveiling her bump without saying a word. https://twitter.com/BET/status/982844710896263168?ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fwww.her.ie%2Fentertainment%2Fmonths-denials-cardi-b-reveals-pregnant-best-way-397595 Performing single 'Be Careful' on Saturday Night Live, the singer didn't speak about her baby news but rather had the camera pan out from her face, showing her stomach.
