Justin Timberlake returned to The Tonight Show this week and that means one thing - the history of rap. This time around, Timberlake and host Jimmy Fallon featured the musical stylings of Drake, Kendrick Lamar, the Beastie Boys, Salt N Pepa, and Canada's very own Snow. Yaasssss Informer!

The music-themed episode didn't stop there. Next up was comedian Ellen DeGeneres, who went head to head against Fallon on Lip Sync Battle. The first-time silent performer pulled out all the stops, giving a passionate and silent rendition of Diana Ross' Do You Know Where You're Going To and a hard hitting performance of a surprising Rihanna track.

Ending out the packed show was Macklemore and Ryan Lewis, who were joined onstage by Eric Nally, Melle Mel, Kool Moe Dee and Grandmaster Caz for their high-energy performance of Downtown. We just can’t get enough of this song or those knee drops!
Watch The Tonight Show Starring Jimmy Fallon weekdays at 4E/1P on Much.
