The cutest celebrity BFFs reunited last night on The Tonight Show Starring Jimmy Fallon – Justin Timberlake and Jimmy Fallon opened the show with their classic bit, and with help from the coolest band in the world – The Roots. JT just can’t go on the show without them breaking into song. I love it! What am I talking about? Everyone loves it! They start with “Fiesta” by R. Kelly and Jay Z, and end with “Fight For Your Right” by The Beastie Boys.

Watch The History of Rap 6 video below.

Everyone knows Jimmy Fallon is my boyfriend, but you cannot keep your eyes off Timberlake when he is in his wide-eyed comedy mode, mixed in with his singing and dancing.

Justin had to hold Jimmy back, when he got all into singing the first line of “Straight Outta Compton.”

JT: “Jimmy, we talked about this. You are not straight outta Compton. You’re straight outta upstate New York.”

And what was the lesson learned?

You don’t “lick your boom-boom down.”

The Tonight Show Starring Jimmy Fallon airs weeknights at 11:35pm ET on NBC.
