6. KIM KARDASHIAN

Given how her infamous Elle photoshoot with Bieber was arguably the most hyped-up magazine look of 2010, Kim Kardashian's fever is no secret. Not to mention, his Twitter announcement that Kim was his new girlfriend (and her confirmation) not only sent 10-year-old chicks into enraged, psychotic shitfits, it also indirectly influenced Pauly D's new hairstyle. That's it. We must concede; the evidenced power of Bieber makes us official Beliebers.
