Justin Timberlake started teasing us yesterday via Instagram, but lived up to the hype last night. Ready for the next piece of the 20/20 Experience -- 2 of 2? Check it out here.

Justin has explained that the second half would be a little more intense and grown up compared to the first half.

Justin compares part one to dating your high school sweetheart, "If you could imagine you're 16 and she's everything you thought. She's Marilyn Monroe and then you meet her older sister; everything that's dark and wrong about her at that age is why you become infatuated with her."

So here it is the new single from the 20/20 Experience -- 2of 2, TKO.
