Elton John and Eminem (2001)
When Eminem performed at the 2001 GRAMMYs, no one anticipated him bringing along music legend Elton John. You don't get stranger musical—or fashion—bedfellows than these two. But, trust us, once this pair launched into the Detroit rapper's stalker hit "Stan," fans couldn't believe this was only the first time they performed together on stage.
Eminem's gritty lyrics were accompanied by Elton's award-winning vocals for a rendition of the song that still blows us away 15 years later. The most unforgettable moment of the performance, however, was when the two men embraced in a big hug at the end of the performance.
