Cardi B previewed a new song at a VMAs afterparty last night

Motherhood isn't stopping Cardi B from working her ass off. Last month, the self-proclaimed Empress divulged that she has a new project dropping this fall. Then, last night, following a handful of triumphant wins at the VMAs and one memorable acceptance speech, she headed to Atlantic's afterparty at Tao Downtown where she played a brand new track. In the song, Cardi boasts that she's "the queen of talking shit and backing it up." Hear a snippet of the new cut below.
