17. Eminem and Elton John
Eminem and Elton John first met in the early 2000s, when Eminem performed with Elton John the song “Stan” on the stage at the Grammys. They remained friends and Elton has even helped his friend battle with addiction. Eminem said that he called Elton John when he wanted to get sober, “because he’s somebody in the business who can relate to the lifestyle and how hectic things can be.”
