Whoa, Nelly! We've been fans since the Canadian singer's debut album came out in 2000, where she told us, before The Notebook made it cliché, that she was a bird. Over the past 12 years, we've watched Nelly evolve from the typical singer-songwriter to the not-so-innocent sex pot. Having worked with Timbaland, Pharrell and Justin Timberlake, it's easy to see why her third album, Loose, made her an international star, selling more than 10 million worldwide.
