Christina Aguilera Naked Instagram Selfie: Christina Aguilera, who had a hit with the song "Beautiful," hit Instagram with a topless selfie to show she is still a fighter and it's not dirrty.

The Voice coach posed for a selfie in a bathroom mirror wearing nothing but a pair of pink panties and  a leopard print fedora.

Aguilera, who is the mother of two small children, joined the nude selfie trend.

"Just so you know with me, it's all real, all the time," Aguilera captioned the nearly nude Instagram selfie.

"Felt like it was time to start sharing some personal stuff with you guys... And it's just the beginning. Night night. X."

Aguilera recently took on her old friend and rival Britney Spears with a spot-on impression.

Aguilera, 34, welcomed her daughter Summer Rain in August of 2014. Aguilera is mother to six-year-old son Max from her previous marriage to Jordan Bratman. Christina and Bratman married in 2005 but split up five years later. Their divorce was finalized in April 2011.

Christina Aguilera has always been a sensually-forward artist. The "Genie in the Bottle" singer once told Maxim, "I've never been one to shy away from my sexuality."

On the "Tonight Show" last year, she said "I'm an artist, and expressing myself in a sexual way, no matter how that changes throughout the years, is something that has always come naturally to me. At this point of my life, I'm 32 and I feel sexier than ever because you know what you want. So it was all about -- the shoot, yes I was in control of that -- but it was all about appreciating the woman I've become, and effortless sexy, not trying too hard."
