At one point and time, Christina Aguilera was crediting her hubby for inspiring songs like "Ain't No Other Man." Now, Jordan Bratman is reportedly being blamed for bringing down his estranged wife's career.

According to a report, Christina -- who recently filed for divorce from Jordan after nearly 5 years of marriage -- thinks Bratman is at least partly responsible for the disappointing response to Bionic.

"She feels that he held her back when she wanted to focus more on her career," an insider claims.

Uh-huh. Kind of makes you wonder how she found so much time to film that major acting role of hers. (Burlesque, co-starring Cher, opens this Thanksgiving.)
