No hip-hop track was safe during Justin Timberlake and Jimmy Fallon's History Of Rap 6 collaboration. Drake, NWA, Kendrick Lamar and Fetty Wap were among the artists whose songs were covered during the hilarious segment on The Tonight Show Starring Jimmy Fallon.

The six-minute spoof kicked off with the late-night talk show host and his guest Timberlake, 34, rapping a few lines from R Kelly and Jay Z's Fiesta before launching into LL Cool J's classic Rock The Bells. Giving the audience a reminder of the most iconic hip-hop songs, the duo then ran through a throwback medley, which included Public Enemy's Fight The Power and NWA's Straight Outta Compton.

Fallon, 40, showed off his impressive lyrical skills by rapping Busta Rhymes' notoriously hard verse on Chris Brown's Look At Me Now before he and Timberlake performed modern tracks, including Kendrick Lamar's B***h Don't Kill My Vibe, Fetty Wap's My Way, Drake's Know Yourself and Ace Hood's Bugatti. At one point, the close friends break out MC Hammer's iconic Hammer Time dance.
