Justin Bieber threw it back to his old 16-year-old hairstyle with the bangs coming down over his forehead while slightly slanted to the side.  He also threw in a new mix to his old style, reminiscent of Rihanna, with the side of his head shaved down to a Caesar style cut.  One of his back-up dancers tweeted about his old look making an appearance in 2013.
