OTRC: Christina Aguilera semi-nude photos leaked online by hacker

Christina Aguilera speaks to OnTheRedCarpet.com at the Los Angeles premiere of 'Burlesque' on Nov. 15, 2010.

Photos of Christina Aguilera posing semi-nude were posted online recently and the singer's spokesperson says they were leaked by a computer hacker, who will be pursued "aggressively"

Aguilera recently made her acting debut in the musical film "Burlesque", which is currently in theaters. In the pictures, she poses in a revealing outfit that appears to be made of sequins, as well as in a robe and a see-through t-shirt while standing inside a room covered in a leopard-print rug.

"The photos of Christina Aguilera being leaked to the press were illegally obtained by a hacker who tapped into Christina's personal stylist's account," her spokesperson told OnTheRedCarpet.com. "The photos were taken in the privacy of Ms. Aguilera's home and were used only in a personal exchange between the star and her stylist."

The pictures of Aguilera were posted on various websites, including egotistic.com (Warning: Contains explicit content).

"We are attempting to determine the identity of the hackers and will pursue them aggressively," the singer's spokesperson added. "Their conduct is reprehensible."

In "Burlesque", singer Cher portrays Tess, a nightclub proprietor and headliner who is struggling to keep the place open. Aguilera plays Ali, a small-town girl who moves to Los Angeles and begins working at the club as a cocktail waitress, aiming to one day perform on stage.
