Not only has Cardi B and Megan Thee Stallion's raunchy Grammys spectacle been dividing fans all week, it has now led to a potential legal battle.
And it's all over a Twitter squabble.
Never one to back down to a troll – Cardi B has landed herself in hot water after posting a fiery response to conservative US political commentator Candace Owens' harsh criticism of the X-rated performance. Owens is now threatening to slap Cardi with a lawsuit for "slandering" her family.
After tweeting that Cardi was "at her worst" during the first ever live rendition of rap hit WAP, the rapper responded by dredging up an allegedly fake tweet about Owens' husband having an affair with her own brother.
