12. Christina Aguilera
After a terrible start to 2011 that included the flubbing of the National Anthem at the Super Bowl, a tumble on the stage at the Grammys, a plagiarism lawsuit, a silver screen flop with “Burlesque” and a painful public divorce, Christina Aguilera seems to be rising from the ashes like a phoenix with a four-octave range – thanks in large part to her gig as judge and vocal coach on hit show “The Voice” and her cameo on Maroon 5’s No. 1 hit “Moves Like Jagger.” A new album is expected in summer 2012, so look for a major resurgence. —Jeff Royer
