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.
