Rapper 2 Milly has filed a lawsuit against the makers of 'Fortnite'.
The Brooklyn-based star has hit out at Epic Games, accusing the company of illegally using a dance he created in the world-famous video game.
The case - which has been filed in a court in Los Angeles - sees Milly accuse the North Carolina-based company of misappropriating his dance moves without giving him compensation or credit.
The dance, which is otherwise known as Swipe It, is one that players can buy for their characters on the game, and is taken from the Milly Rock.
Milly created the dance in 2011, but it became hugely popular in 2015, when loads of big-name stars were seen performing their own version of it.
Meanwhile, Epic Games recently announced it is launching its own online games store to rival Steam.
The creators of the most popular game of the moment will open the Epic Games Store in 2019.
Epic Games CEO Tim Sweeney said: "Previously, most creators were not compensated by game developers for their work and instead had to rely on donations.
"By matchmaking creators with developers, the Epic Games Store makes it easier for players to discover games, and rewards content creators for their efforts."
