Eminem performs 'Lose Yourself' during surprise appearance at Ed Sheeran's Detroit concert

The audience at Ed Sheeran's concert in Detroit on Saturday lost themselves in the music when Eminem showed up for a surprise hometown performance.

In videos posted to Sheeran's Instagram page on Sunday, the singer keeps the surprise close to the chest by telling his audience he wanted to perform a "cover" of an Eminem song.

As Sheeran strums his acoustic guitar while singing his rendition of the iconic opening lines of Eminem's "Lose Yourself," the rapper is seen stepping on the stage to join in on the second verse as the crowd cheered.

"Detroit. What a moment," Sheeran wrote in the caption.

In other videos posted on social media by concertgoers, Sheeran is seen telling the crowd that Eminem was only going to come on and do one song.

"And I said, 'you can't come on in Detroit and do just one song.' Do you want another song?" Sheeran said.

The duo then performed Eminem's 2000 hit "Stan," with Sheeran filling in Dido's vocals during the chorus. Sheeran previously appeared on stage with Eminem in November to perform the same song when "The Real Slim Shady" rapper was inducted into the Rock and Roll Hall of Fame.
