Justin Timberlake performed "Suit & Tie" with Jay-Z on Saturday Night Live last night.

JT gave the grown-and-sexy anthem a dignified showing, complete with a band ("The Tennessee Kids") and a handful of gangly dancers. Showman that he is, he even busted out a dance move or two himself.

Jay-Z was all black everything -- jacket, shirt, pants, etc -- with his classic Roc-A-Fella medallion as the centerpiece in a neck full of jewelry.

Justin also performed "Mirrors," the second single from his upcoming album.
