Each year, the Grammy Awards puts together some of the most memorable moments in music with unforgettable collaborations.
Music's biggest night is the ideal place for artists both old and new to come together and make history live on stage.
Check out 10 of the most epic Grammy duets below.
1. Lady Gaga and Elton John
If there was an award for the most theatrical GRAMMYs debut, Lady Gaga would be a definite contender. In 2010, Mother Monster took viewers through the "Fame Factory" and emerged from the ashes seated at a double-sided piano with Elton John. The two served up an unforgettable duet of Gaga’s “Speechless” and John’s “Your Song.”
2. Prince and Beyonce
Years before Queen Bey claimed the throne, she bowed down to the one and only Prince. In 2004, Beyonce shared the stage with the Purple One for a fierce medley of “Purple Rain” and “Crazy in Love.”
