Rihanna transformed YouTube with her music and songs and Instagram with her dress sense. Her tattoos and new album (including the new song 'Better Have My Money') keep her in the news. If you're wondering just how old is Rihanna, her young age might surprise you, especially since the 'Diamonds' singer has been in the daily music charts for a decade. From Rihanna's hairstyles (including short hair and red hair) to her nails to the launch of Rihanna perfume, the good girl gone bad knows beauty just as well as fashion and style.
