He wowed fans with his "Saturday Night Live" antics last weekend, and all this week, Justin Timberlake is bringing the fun to "Late Night With Jimmy Fallon."
On Tuesday night, that meant bringing "SexyBack" -- old school.
Joined by Fallon and the Ragtime Gals -- aka the usual "Late Night" players -- Timberlake donned a bold-striped blazer and straw boater as he harmonized his way through the 2006 hit.
Watch him "take 'em to the chorus" in the clip below, and see what Timberlake has in store next on Wednesday night's episode of "Late Night."
