Rihanna played the chameleon this year, endlessly changing up her hairstyle and sexy style. People love her, no matter what the look — Rihanna even clinched Esquire's 2011 sexiest woman alive honor.
Rihanna released her latest album, Talk That Talk, over the holidays in 2011. She later made headlines when she released two new collaborations with Chris Brown. Better received was her "Princess of China" track, made with Coldplay. She even won a Grammy in 2012 for best rap/sung collaboration.
Rihanna took a break from music to promote her first big-screen project, Battleship. The blockbuster wasn't a big hit, but she's already lined up new gigs. Rihanna will be a lead voice in the animated film Happy Smekday!, and also filmed a part for The End of the World. She's further expanding her empire with multiple fragrances.
