Christina Aguilera is one of the biggest pop stars of our time, and she is the second, top-selling single artist of the 2000’s, just behind Madonna.

She is currently a coach and a judge on the NBC hit reality talent show ‘The Voice’ alongside other pop and country sensations Cee Lo Green, Adam Levine and Blake Shelton.

Christina continues to work as a recording artist – her seventh studio album is scheduled to be released later this year.

Incidentally, we are still waiting for her and Britney Spears to do a Playboy centerfold spread together -- is that really too much to ask?
