Saturday Night Live enlisted another Justin for double duty: Justin Timberlake announced on Twitter (via Stipple) that he’ll be the host and musical guest on the March 9 episode of SNL. It’ll be JT’s third time headlining both slots, and his fifth time hosting. Most recently, he hosted in May 2011 with musical guest Lady Gaga.

But in the days leading up to the March 19 release of The 20/20 Experience, Timberlake’s comedy-music hype machine isn’t just stopping at Studio 8H.

JT will also appear as the guest and performer on Late Night with Jimmy Fallon the following week, from March 11-15. It’s the first time that show has had an artist do a week-long residency. Guess that means it’s time for another volume of The History of Rap!
