Justin Timberlake to host ‘Saturday Night Live’ again!

Justin Timberlake will be back hosting “Saturday Night Live” in all his “... In a Box,” “Give It on Up” and “Mother Lover” glory, an NBC Twitter slip-up has revealed.

The singer-turned-actor, who earned two Emmys thanks to his previous stints on the sketch comedy, will be hosting for the fourth time on the May 21 season finale. He’ll be live from New York a few weeks after Tina Fey is slated to host on May 7 (more Sarah Palin, please!). The news came via a wayward response on NBC’s official Twitter feed.

“I didn’t realize that @nbcSNL isn’t back until May 7th!!! What am I going to do!? Is Tina Fey the season finale!?” a fan wrote.

“Nope! We have Timberlake after that!” was the response, which has since been removed from the micro-blogging site.

His musical guest will be Lady Gaga, who has been just about everywhere promoting her “Born This Way” album. Gaga last performed on the “SNL” stage in 2009.

If Timberlake is indeed the host, we hope Gaga jumps into some of his sketches.
