This song makes me so angry.

As some of you may know, the song is apparently based around Britney and Justin's break up in 2002, and the song speculates that Britney cheated on him, hence why they broke up. Then in the music video, he uses a Britney lookalike and basically recreates a break-up, then furthermore in an interview he said that the song has no relevance to his relationship with Britney. Then why the lookalike and certain lyrics?!
