Jimmy Fallon, Justin Timberlake Go '#Hashtag' Happy; Questlove: 'Shut the F— Up' (Video)

Does the former ‘N Sync frontman know that the “Late Show” job is spoken for when Fallon leaves?

Best friends Jimmy Fallon and Justin Timberlake sure  hang out a lot. Like, a lot a lot.

The duo have yet another collaborative video, which aired on “Late Night” Tuesday. It's called “#Hashtag,” and it shows what a Twitter conversation would be like in real life.

The skit has its hilarious moments (Fallon's Ray Romano impression), its annoying ones (the repetition) and even a redeeming conclusion:

At the end, the Roots’ Questlove enters Timberlake's dressing room with a simple message for the BFFs: “Hey guys, hashtag shut the f— up.”
