Christina Aguilera shares sexy naked bathtub snaps on Instagram.

Strategically placed soapy bubbles ensured the images weren't x-rated as the Lady Marmalade hitmaker soaked in a marble tub.

In one image the mother-of-two is pictured leaning back over the side of the bath as she covered her breasts with her hands. 

Another photo showed the Dirrty hitmaker in a larger tub with her back to the camera but flashing a sultry look over her shoulder.
