According to TMZ, 2 Milly is suing the makers of the incredibly popular game Fortnite Battle Royal for stealing the "Milly Rock".
The rapper filed legal docs this week against Epic Games -- the company that makes Fortnite Battle Royale -- for allegedly using his popular Milly Rock moves in the game without his permission to capitalize on the popular dance craze ... and make a ton of cash.
2 Milly wants the game to pay up AND remove the dance from their games.
Do you think he has a case? Can you even copyright a dance move?? The video above addressed that question.
