Christina Aguilera's Sexiest Ever Photo Shoot

She's back to her Dirrty best...

She may have a 9-month-old baby into tow but it's clear Christina Aguilera has no intention of toning down her Dirrty image.

Posing in just a bra, a barely-there micro-mini and thigh-high PVC boots, the singer looks better than ever in her a shoot for her new album Keeps Gettin' Better.

The blonde bombshell showed off her new skinny figure after working hard to lose the post-pregnancy weight.

The new album is set to be released in November and will be a greatest hits compilation, including two new tracks Keeps Gettin' Better and Dynamite.
