Aguilera played it safe as a fresh-faced teen idol. But now? The 31-year-old Voice coach isn't afraid to experiment with accessories and curve-hugging silhouettes. "I like to keep it fresh and interesting," she told Us Weekly about her style on the singing competition. "I get bored and I'm an artist first and foremost . . . I love theatrics."

The Dreamgirls star--and former American Idol contestant--famously dropped 80 pounds following her Oscar-winning role. She admitted to Stylelist earlier this year that it took some time to get used to her new shape. "Because it's a new body, I'm trying to find out, how do I want to be perceived? Who is this new me? I knew how to be the big girl, but now I have to find out how to be this girl," Hudson explained about learning to dress her new shape.
