We knew Rihanna was a busy lady… but we didn’t know she only got four hours of sleep each night.<br /><br />The singer revealed to Vogue Paris that not only does she struggle to switch off at the end of every day, but that she hardly gets any winks at all.<br /><br />Bad girl RiRi says that even when she gets home early after a hard day of work, which means before 1 am, she starts binge-watching shows or documentaries because she can’t go straight to bed. And as a result, she only gets three of four hours of sleep at night.<br /><br />But hey, she somehow seems to make it work.<br /><br />Not only is she a bonafide superstar in the music world, but she’s got her own fragrance line, she’s ventured into fashion, philanthropy, hosting gigs, acting, and even release her own book.<br /><br />So imagine what she could do with a full night’s sleep.<br />
