Charli XCX and Kylie Jenner are among the celebs who've copied Kelley Heyer's viral dance to the song.

Ms Heyer's legal team claims Roblox made $123,000 (£93,000) from selling the moves as an "emote" - a celebratory animation used by players in the game - without her permission.

Roblox has even published an emote to the Marketplace called “Charli xcx - Apple Dance” and sources have said the artist has created an account.
