This is nothing new regarding Justin Timberlake.
He's always been an opportunist piece of ****. He took what he needed from Britney to promote his upcoming 'solo' musical career and used everything in his favor after the breakup. Not only with Britney, but also with all the songs of his debut album, that is complete of rejects songs from Michael Jackson. The same happen again with Janet Jackson. He is a total crap. Even with his wife he is a lame douche bag.
Even now, after the documentary, magazines are 'still' on his side and defending him, because he is a man and man can do whatever they want and its ok.
Cry me a ******* river, indeed.
