Mike Tyson, who is coaching Chris Brown ahead of his matchup against Soulja Boy, is stepping into the studio to give his student a leg up in the race.

The boxer is trading places with Brown, recording a diss track against Soulja Boy ahead of the rappers’ celebrity boxing match.

On Jan. 9, Tyson teased the track, “If You Show Up” along with a photo of himself working in the studio. “In studio. Dropping heat. Wait and see what this is about,” he tweeted.

“If you show up, it’s going down. I’m gonna teach up how to knock your a** out,” the opening lyrics of the song read. “I’m talking sh*t, cuz I’m the champ. Soulja Boy you don’t stand a f***ing chance. Chris Brown is gonna make you sh*t your pants.”

Tuesday’s release of the song is accompanied by an odd video featuring scantily-clad women singing along to the song.

Soulja Boy and Chris Brown took their animosity to the next level when they agreed to turn their feud into a physical battle earlier this month. The feud between the rappers began on Jan. 3 after Soulja Boy liked a photo of Brown’s ex-girlfriend Karrueche Tran on Instagram.
