While Usher has experimented with his look a bunch throughout the years, he's mostly known for having his iconic short Caesar cut. Apparently, the star is ready to change that, because he posted a new hairstyle to Instagram that we won't be able to get out of our heads. The singer is now wearing his hair in a retro-looking pompadour, a style that is long and tall on top of the head that was popular in the '50s and '60s and had fans like Elvis, Desi Arnaz (who you may know as Ricky Ricardo on I Love Lucy), and Little Richard. With such iconic devotees, it's no wonder Usher decided to try it out for himself. Check out his more classic looks, ahead.
