The 22-year-old is known for his song Watch Me (Whip / Nae Nae), which he wrote in his basement at the age of 17 and released on YouTube.
The track went viral and inspired a dance craze, which earned him a recording contract.
Prosecutors say he has been charged with two counts of assault with a deadly weapon and is currently being held in prison on $ 105,000 (£ 79,000) bail.
