In the wonderful world of music, collaborations happen all the time – practically on a daily basis. But in some cases, you never would have thought to put the two artists together. And that's when the magic happens.

The Grammy Awards is the biggest night in music and one of the best award shows around. Besides the fact that stars like to go all-out with their red carpet looks –- we're looking at you, Nicki Minaj –- the performances are seriously epic! And they kind of have to be, since there's a new one after every other award.

The show has a tradition of teaming up different artists to put on one hell of a collaborative performance. This year, we’ll see Song of the Year nominee Ed Sheeran take the stage with the one and only Elton John -- a.k.a. the ultimate ginger singing duo!

Plenty of other greats have performed with the musicians of today. Take a look at the most memorable collaborations that have hit the Grammy stage!
