Going by numbers alone, Rihanna is already written into the history books in bold ink. Her digital sales add up to 100 million – more than anyone, anywhere, ever. Her catalog of hits includes a dozen Number One smashes, from 2006's "SOS" to 2012's "Diamonds" – the same number as Madonna and the Supremes, and more than anyone else except the Beatles, Mariah Carey and Michael Jackson. But Rihanna's appeal transcends statistics. She's a star in the truest sense: a wild, larger-than-life personality you just can't look away from. Tabloid wildfires may rage all around her, but she shines bright through it all.
