Tommy Robinson just launched a barb at US rap star Eminem, suggesting he didn't know anything about politics.
Eminem has hit the headlines today with a new song about Donald Trump, heavily criticising the US President.
But Robinson, the former leader of the English Defence League known for his hardline views on Islam, appears to have little sympathy for the 8 Mile star.
Robinson retweeted a message which read: "Eminem went from "imma murder muh girlfriend" & calling everyone "fag" to pretending he knows stuff about politics.
"Sorry, but no."
Eminem has yet to respond to the attack.
