Cardi filed the lawsuit against Latasha K -- who has a blog called unWinewithTashaK. She's pissed about 23 videos Tasha's posted over the last 14 months.
According to the suit, Tasha posted a video last April saying Cardi's baby might be born with intellectual disabilities.
The inference seems to be Cardi was doing drugs that would harm then-unborn Kulture.
She's also suing Starmarie Ebony Jones, who, according to the suit, posted a video in September accusing Cardi of doing Molly, cocaine and engaging in prostitution.
Jones allegedly says of Cardi, "Just a Grammy nominated prostitute running around spreading her herpes."
