Yesterday, Cardi shut down reports claiming she had officially reunited with the Migos rapper.

Update: Cardi B was in court Thursday morning for a hearing in her strip club fight case, and as she was leaving, she commented on the status of her relationship with Offset. When asked how things are going on that front, Cardi responded, “We’re working things out, baby.” There have been signs pointing towards a potential reunion, and now TMZ is reporting that the two are back together. However, Cardi B said that isn’t true: A bit after 9 AM EST this morning, Cardi wrote in a tweet that was quickly deleted, “TMZ why ya be lying. I haven’t even been in Atl since Christmas.” (UPROXX)
