Ed Sheeran has credited Eminem's "The Marshall Mathers LP" for helping get rid of his stammer as a child.
During an appearance on "The Howard Stern Show" last week, the "Shape of You" singer said he received the album as a gift when he was 9 and found that he stuttered less while rapping along.
"By learning that record and rapping it back to back to back to back, it cured my stutter," he said.
Ed Sheeran went on to detail the friendship he has developed with Eminem since they first met in 2017.
"I think it's different with Eminem because he is quite reclusive, doesn't see or meet that many people," said Sheeran. "I've known him now six years and we've done three songs together, I've played with him twice on stage. He's another person I really relate to, as he lives in his hometown still and has his ecosystem around him."
Last year, the pair performed "Stan," Eminem's 2000 hit featuring Dido, when the rapper was inducted into the Rock and Roll Hall of Fame.
Sheeran recalled getting the call to do the duet and, despite being in the middle of shooting a music video, felt it was too good of an opportunity to turn down.
"I was like, 'I can't say no. I can't,'" he said. "So, I got a plane straight after my music video, flew there for the song, and then that night flew back. It was really worth it."
Sheeran released his sixth studio album "Subtract" on May 5, which scored him his sixth No. 1 album in a row in the United Kingdom.
His latest release is also the UK's fasting-selling record of 2023 so far, having shipped 76,000 units in its opening week.
The release of "Subtract" comes off the back of Sheeran's high-profile "Thinking Out Loud" court case.
Sheeran was being sued by the heirs of Ed Townsend, who cowrote Marvin Gaye's "Let's Get It On." They alleged that his 2014 song "Thinking Out Loud" had copied elements of Gaye's 1973 soul classic.
Weeks ago, a Manhattan court ruled in favor of Sheeran, finding that he didn't plagiarize Gaye's song.
