Christina Aguilera has denied reports that DJ Samantha Ronson is one of the reasons the singer has filed for divorce from husband Jordan Bratman.

"[It is] a good, longtime friendship and nothing more than that," a rep for Aguilera told the Chicago Sun-Times.

Aguilera and Ronson have been photographed spending time together in the days following the split. Ronson was previously romantically involved with Lindsay Lohan.
