Posh duo: Justin Timberlake & Jimmy Fallon present ‘History of Rap 6’

US Weekly has reported that the impressive music idea of two stars was backed up by Fallon’s house band The Roots as they sang and rapped their way through a big amount of classic hits from MC Hammer, LL Cool J, The Beastie Boys and Public Enemy.

The straight faced, clean cut duo got totally into their performances, but new dad Timberlake did draw the line when his show host attempted to take on N.W.A.’s “Staight Outta Compton.”

“No, no, no,” he chastised his buddy. “We’ve been through this before. You are not straight outta Compton. You are straight out of upstate New York.”
