Controversial rapper 6ix9ine is facing a copyright infringement lawsuit from South Carolina artist Warren Hamilton, who said he’s used the name “SIX9” since 2007.

Per legal documents viewed by Complex, and initially reported on by Billboard, Hamilton claimed that Daniel ‘6ix9ine’ Hernandez has “injured and stifled” his career after he started releasing music under the very similar name in 2017. Hamilton claims that he first used the name SIX9 in 2007, and has released multiple projects under the name. He’s also toured as SIX9 across the country, performing in venues alongside the likes of Lil Wayne. His most recent release as SIX9 came in January, 2022.
