Justin Timberlake included a little jibe at Kanye West in his Saturday Night Live performance last night ... getting back at the rapper for criticizing his new single "Suit & Tie."

Mr. Kardashian dissed Timberlake and Jay-Z's new track during a performance at New York's Hammersmith Apollo, recently, saying, "I got love for Hov, bit I ain't f-cking with the 'Suit & Tie.'"

JT countered with some tweaked lyrics last night. Instead of: "Aww, sh-t so sick, got a hit and picked up a habit," Timberlake altered the words to: "My hit's so sock, got rappers acting dramatic." Wonder if Kanye was listening closely?

Of course, Kanye collaborated with Jay-Z on 2011's Watch the Throne, which was a huge commercial success.

While Kanye's cool with being #1 on the charts, he seems to have a problem when other artists sell albums, which is what lead to a three-minute rant about the negative affects of commercialism on music, during his Apollo gig. And, of course, being on E!'s top-rated Keeping Up With the Kardashians and impregnating reality TV's biggest star isn't bowing to commercialism at all, is it, Kanye???
