Christmas in September?

It certainly feels like the festive season has come early to Late Night. And that’s because Justin Timberlake is joining his pal Jimmy Fallon every Tuesday this month for “Timberlake Tuesdays” as he counts down the days till his new album, The 20/20 Experience: 2 of 2, is released on Sept. 30.

And that’s definitely a cause for celebration.

We didn’t think that the besties – who we caught joking around backstage on Tuesday in this exclusive photo (click on it for more) – could top their History of Rap, but they managed to do it last week with a little thing called The Evolution of End Zone Dancing.

What do they have in store for viewers Tuesday? Tune in to NBC at 12:35 p.m. to find out.
