On Saturday, Lil Durk performed alongside Rod Wave, Latto, and Moneybagg Yo for MLK Freedom Fest at the Bridgestone Arena in Nashville.

According to Rolling Stone, the Chicago rapper brought out surprise guest Morgan Wallen to perform their joint song “Broadway Girls.” Before his controversial guest came out, Durk introduced him by saying Wallen was “genuine at heart.” Durk added, “Can’t nobody cancel shit without me saying it, you know what I’m saying?

Wallen’s success story came to a halt when a viral video surfaced of him using a racial slur. It caused Spotify, Apple, and some radio stations across the country to remove his music from playlists. Wallen’s record label Big Loud also suspended his contract “indefinitely” in wake of the video.

He issued a statement to the New York Times, apologizing for his behavior.

“I’m embarrassed and sorry. I used an unacceptable and inappropriate racial slur that I wish I could take back. There are no excuses to use this type of language, ever. I want to sincerely apologize for using the word. I promise to do better.”
