You know how your mom always told you to wear clean underwear everyday in case you get hit by a bus? Well, Chris Brown certainly took that to heart! He only wears a pair of underwear once, and then throws them away! "I'm not a germophobe, but I don't feel like washing them 'cos I'm always moving, so I buy different packs," he tells Starpulse. "I buy like five or six packs... and I'm good for, like, a week and (then) I gotta get a whole lot of new drawers." We remember hearing the same thing about Britney Spears a few years back (before she went through her commando phase), but c'mon, it's called detergent, people -- use it!
