Cardi B got into a verbal altercation with a fan on Twitter, and Cardi B threatened the woman with violence, and told the woman that her 2 month old baby had a "big alien head."

It all started when a woman named Nicki was on Twitter and made remarks about Cardi's daughter Kulture. Nicki said that she thought Kulture, "would be prettier," but conceded that Cardi's daughter was "cute."

That caused Cardi to fly into a tirade and call the girl's son an "alien head."

For those interested, here is a picture of Nicki's son - who is very cute.

Cardi then went to the girls page, looked through her photos, and realized that Nicki's babys father did not attend the baby shower. Cardi then went in for the kill:
