An edited video has been blowing up of a Cardi B rant where she was defending her debut album, pointing out how hard she worked on it while expecting her first child. A group of 10 year old "rappers" called Z n8tion had a Cardi B diss track that hurled several insults at the female rapper. Alongside some clever editing and perfect timing, the video made it seem like the superstar was going toe to toe with some 4th graders, but that's not the case.
