Christina Aguilera: Raunchy Photos Surface

In the latest development in Christina Aguilera's post-divorce drama, RadarOnline has revealed that hundreds of private photos of the Burlesque star have surfaced, including pics of her in bed with boyfriend Matthew Rutler.

Other photos showcase the starlet's raunchy behavior at Nicole Richie's bachelorette party in September 2010. Aguilera was photographed posing with two naked strippers and mimicking oral sex acts on a sex toy and a banana.

An unidentified man shopping the revealing pics told RadarOnline that he found them on a discarded digital storage card in a French hotel where Aguilera and Rutler had stayed.

Aguilera, who filed for divorce from ex-husband Jordan Bratman in October 2010, was the target of another nude photos leak in December 2010, in which a hacker stole semi-naked pictures of the singer from her stylist's computer.

Earlier this month, she and Rutler were arrested for public intoxication. Rutler was slapped with a DUI. In February, Aguilera reportedly resisted her staff's requests that she get help for her drinking problem.

Some experts suggest that if the star continues behaving erratically, her custody rights could be challenged in court. Aguilera has one son, 3-year-old Max, with her ex-husband Jordan Bratman.
