It took a flop marriage, flop album and hit TV show, but finally Christina Aguilera keeps getting better. Nasty, her collabo with her co-judge from The Voice, is supposedly an outtake from Burlesque sessions, but actually puts the majority of that soundtrack to shame. It's funky and another showcase for her unmistakable howl. Following its leak, Ceelo has suggested the two might perform it on their show, but I'm happy for @therealXtina to get on @therealTreadmill for 6 months first and then do something musically. I'm kidding of course - I love chubby Christina, and truthfully want more songs like I Am and All I Need.
