Not so Dirrty! Christina Aguilera finally ditches the hotpants and scary make up to promote news series of The Voice

She is renowned for her misfiring fashion sense that often leads to more jeers than cheers.

But Christina Aguilera scored a rare success in the clothing stakes after donning a silk blouse and black short skirt as she promoted the next series of her hit talent show the voice.

The 30-year-old appeared alongside her fellow judges Adam Levine, Cee Lo Green, Blake Shelton, and host Carson Daly.

But it was Christina who shone the brightest as she appeared looking fresh-faced, with a tastefully subtle make-up look.

The reality show’s creator Mark Burnett has revealed each judge will mentor twelve contestants instead of last year’s eight, which possibly means more rounds of blind auditions.

Christina also said she and her fellow coaches will open with a 'kicka**' musical number.

The show is sure to attract plenty of viewers when it returns on February 5 after the Super Bowl.

Christina is certainly having a busy time at the moment.

She will be joining popular teen idol Justin Bieber, Mary J. Blige, and Kelly Clarkson at the American Music Awards next month.

Producer Larry Klein unveiled the latest group of AMA entertainers on Monday. They join previously announced performers Katy Perry and Pitbull.

The Genie In A Bottle star will be performing Moves Like Jagger with Maroon 5, who are led by her fellow judge Adam Levine.
