Sir Elton John has revealed that he and Eminem have an unusual nickname for themselves - “c*nt”.

The singer made the admission in an interview with Rolling Stone, during which he also spoke about the rapper's successful battle against addiction.

“We have such a laugh. We call each other c*nts,” he said, reports Rap-Up. “I ask him how he’s doing and tell him how proud I am of him.”

Sir Elton, who became friends with Eminem after they performed at the Grammy Awards in 2001, added: “I love him. I don’t see much of Marshall, but we speak a lot.

“He’s really worked very hard at [sobriety], and it’s changed him so much. I just saw a picture of him in a magazine, and he looks like a 17-year-old boy. I’m so happy for him.”

Elton John is currently promoting his new movie Gnomeo And Juliet, which tells William Shakespeare's love story through the eyes of a gnome.
