Usher looooooooves him some good shopping in Beverly Hills, and we caught him exiting Barney's New York in Beverly Hills today, not too long after Sharon Osbourne departed. One pap asks the soulful crooner to give him a peace sign, and Usher replies with the middle finger! But Usher is just kidding, folks ... he's actually a very friendly, down-to-earth guy, who even spoke with us afterwards to let us know he was really, truly just kidding! We think it's pretty good comedic timing, though: check the video! Peace out!
