Justin Timberlake Does Milli Vanilli on 'Late Night With Jimmy Fallon' [Video]

Justin Timberlake's weeklong residency on "Late Night With Jimmy Fallon" started with a big revelation.

"I'm sick as well," Timberlake told a sniffly Fallon.

"Well, we shouldn't have made out," Fallon replied.

The two old friends joked about kissing during the singer's first interview this week. Timberlake will be performing songs from his new album, "20/20 Experience," every night.

Timberlake touched on his experience joining the "Saturday Night Live" Five-Timers Club, as well as reprising his "D--k in a Box" character (whose name, apparently, is "Raif"). He and Fallon also slyly talked around his subtle knock back at Kanye West. Timberlake had changed his "Suit & Tie" lyrics Saturday night to include a line about "rappers being dramatic" after West had dissed the song.

"For the record, I absolutely love Kanye," Timberlake said.

Then, Timberlake did an impression of Fallon, and the two teamed up to perform a song from lip-synching duo Milli Vanilli.
