Cardi B made a surprise appearance over the weekend at Hot 107.9's Birthday Bash ATL. Cardi joined her fiance Offset and the Migos on stage live at the Cellairis Amphitheatre.

The hip hop stars performed their chart-topping single "Motor Sport" (which also features Nicki Minaj). Wearing a floral dress, Cardi pranced around the stage with a microphone. She recited her verse as the Atlanta crowd screamed. Not to mention, she is 9-months pregnant. A snippet of the performance shows Offset dancing with Cardi while rubbing her stomach.

Back in April, following Broccoli City Fest, Cardi B announced that she will no longer perform at shows due to her pregnancy. Fans were definitely excited and surprised to see her amp up the crowd this past weekend.
