Wowza! Xtina got down right X-rated for her photoshoot with V magazine.

The powerhouse singer stripped down to nothing but her beautiful baby bump for the racy shoot and tells the magazine, “As a woman, I’m proud to embrace my body through all stages of life, staying fearless and confident in surrendering to the unknowns the future has in store.”   Amen, sista!

In other photos, the SASY mom wears a sheer white dress, exposing her nipples,  and laying with her man, Matt Rutler.  This will be the first child for Aguilera and her fiancé.  Christina also has a six year-old son named Max from her previous marriage.
