It's been 16 years since Christina Aguilera got "Dirrty" in the boxing ring, and she's back to giving us those sexy, filthy vibes.
Xtina posted a series of risqué pictures Tuesday on her 38th birthday featuring her husband, Matt Rutler, grabbing a handful for the camera.
Wearing an all-black '80s punk outfit, Christina showcased her amble cleavage in a tight, lace corset.
Apparently, Rutler couldn't help but grab the girls as he matched his wife's "Big 80s mood" with grunge gear and black eyeliner.
But Xtina's husband wasn't the only vulgar action in the shots because she decided to kick it up a notch.
Flipping the double bird, the songbird, who's riding high from her Grammy nom for her duet with Demi Lovato, posted another sexy shot with the caption, "Birthday F*cks."
You know what they say ... once a dirrty girl ...
