Justin Timberlake isn't letting up on his press blitz as he approaches the March 19 release date for "The 20/20 Experience."

On "Late Night with Jimmy Fallon" Tuesday night, the "Suit & Tie" singer donned a different kind of dresswear to perform an old-school, barbershop quintet version of "SexyBack."

Timberlake joined "Late Night's" Ragtime Gals to harmonize a version of his 2006 hit that we're going to have a super-hard time getting out of our heads.

If that's not enough Timberlake for you, The CW also has an upcoming TV special pegged to the release of "The 20/20 Experience."

From 8 -- 9 p.m. ET on March 19, the network will host "Target Presents: The iHeartRadio Album Release Party with Justin Timberlake." (Yep, that's the whole title.) An encore of the hour-long special will air March 22 at 8 p.m. ET.
