3:46 PM PT -- A rep for Vivek Ramaswamy tells us, "Vivek just got on the stage and cut loose. To the American people’s chagrin, we will have to leave the rapping to the real slim shady.”
Eminem is not a fan of Vivek Ramaswamy rapping one of his biggest hits on the campaign trail -- he wants the Republican presidential candidate to lose his music.
The "Lose Yourself" rapper made his feelings known to music licenser BMI after Vivek went viral for rapping some of Em's Oscar-winning track on stage at the Iowa State Fair earlier this month.
In the letter, Marshall Mathers asks BMI to yank his songs from their agreement to stop Vivek from using his tracks.
As a result, BMI fired off a cease and desist letter to Vivek's campaign lawyer last week ... telling them Eminem's objecting to the use of his songs.
Translation: Go ahead and lose yourself, just not in MY music!!!
In the letter, first obtained by Daily Mail, BMI threatens legal consequences should Vivek's campaign keep Eminem's songs in its rotation.
Vivek's fresh off a well-received performance at the first GOP presidential debate and is currently in the middle of a media blitz, including a stop on "TMZ Live," but Eminem's not feeling his vibe.
