JT will host/perform March 9's "Saturday Night Live" and spend a week (March 11-15) guesting on "Late Night With Jimmy Fallon"

Justin Timberlake's crowded promotion schedule for his highly anticipated "20/20 Experience" album just got a lot busier.

In an announcement via his official website the multihyphenate artist announced he'd be serving as both host and musical guest of "Saturday Night Live" March 9. And two days later, from March 11-15, he'll be serving as the first ever weeklong featured guest on "Late Night With Jimmy Fallon." Performances are set for all five nights and chats with Fallon are scheduled for Monday, March 11 and Friday, March 15.

Could "Fallon" viewers be in for "History of Rap," part four?

Timberlake also has a knack for hilarious "SNL" digital shorts like "Dick in a Box" and "3-Way (The Golden Rule)" with Lady Gaga and Andy Samberg:

"The 20/20 Experience" is due March 19 (via RCA), four days after the "Fallon" stint wraps.

JT recently announced that he'll be touring this summer with Jay-Z to promote the new record. Last night, he performed new track "Mirrors" at the BRIT Awards.
