The rapper surprised fans with the news she and husband Offset are expecting baby No. 2 together during the Migos’ performance

Cardi B has been hiding quite the secret — she’s pregnant!

The rapper revealed the news while performing with her husband Offset and Migos on Sunday evening at the BET Awards. After the trio finished “Straightenin,” Cardi joined the group for “Type S—.” Appearing on stage in an embroidered Dolce & Gabbana bodysuit, a sheer panel in the abdomen exposed Cardi’s burgeoning belly. Stylist Kollin Carter gave a behind-the-scenes look at the ensemble, which also included matching leggings and shoes.

The couple are already parents to daughter Kulture Kiari, who turns 3 in July. Offset, 29, is also dad to daughter Kalea, 6, and sons Kody, 6, and Jordan, 11, from previous relationships.

“Cardi B and Offset, giving us life — literally,” host Taraji P. Henson joked when the show returned from commercial following the news break.

“#2! ♥️” Cardi B, 28, captioned an Instagram photo announcing the happy news that went live simultaneously with the performance. She and Offset were married in September 2017. Though the couple has had their share of ups and downs, including a divorce filing last fall, they had reconciled by November and enjoyed a romantic vacation for Valentine’s Day.

Following their performance, Cardi B and Offset were joined by Migos mate Quavo for dinner at Innovative Dining Group’s BOA Steakhouse in West Hollywood. They had spaghetti and meatballs, petit filet, BLT wedges, Cajun-style prawns and crab legs.

Cardi announced her previous pregnancy during a live television appearance as well, revealing the news while performing on Saturday Night Live in August 2018.
