Cristina Aguilera's management has issued the following statement via the artist's website:

It has recently come to our attention that certain pornographic websites are posting sexually explicit photographs and video footage on the Internet fraudulently representing that it is Christina. The video clips advertised on the websites are of a woman with blonde hair shown only from the back--the person in the video is not Christina.

In addition, the person who claims to have taken the video is not, and has never been, associated with Christina or her management. Christina's legal representatives have contacted the website hosts, and Christina plans to vigorously pursue all necessary action against the individuals responsible, including, if necessary, initiating criminal proceedings. We regret that there are individuals who engage in such fraud with no regard for the injury to Christina's feelings or reputation.
