Justin Timberlake books ‘Saturday Night Live’; ‘Fallon’ residency

Get ready for more swooning: The Justin Timberlake comeback machine is seriously revving up.

Timberlake’s much anticipated return to music has already seen the singer deliver a swagger-dipped performance at the Grammys, a smoldering eight-minute single, “secret” concerts around the Super Bowl and the Grammys and take his suave act across the pond to the Brit Awards.

Now as news of the singer and his “Suit & Tie” collaborator Jay-Z headlining London’s Wireless Festival -- there’s also talks of a joint summer stadium tour -- Timberlake is announcing a few more massive promo platforms ahead of his upcoming album, “The 20/20 Experience.”

The singer, who in the last few years shifted his focus to acting, will make his return to “Saturday Night Live” on March 9, where he will pull double duty hosting and performing.

Timberlake’s appearance will be the fifth time he’s hosted the legendary sketch comedy show. His relationship with 30 Rock runs especially deep, considering Timberlake has collected four Emmy Awards for previous stints, including a 2009 prize for a now infamous digital short.

After pulling Saturday night duties, the singer will then set up shop at “Late Night With Jimmy Fallon” for a one-week residency, from March 11 to 15.

During the week, Fallon will interview his buddy, naturally, but more excitingly, Timberlake will perform each night, a first for the show.

“The 20/20 Experience,” Timberlake’s first album in more than six years, is set for March 19.
