Rihanna has fired her business manager after discovering she is worth just $20,000, according to reports.

Patricia Williams claims the Barbados-born chart sensation and her manager Marc Jordan dismissed her after a recent meeting.

But she claims Rihanna's label Def Jam and Jordan are to blame for her financial woes.

Williams tells Blackarazzi.com, "It's not my fault that she only has $20,000 to her name. I'm a professional Business Manager, I have a staff of more than a dozen, I have worked for many high-profile actors, musicians and multi-million dollar corporations. Why would I steal from Rihanna? I showed her all the paperwork and tried to explain to her the circumstances but she wouldn't listen."

"She called me all sorts of horrible names and stormed off. I now feel compelled to share with the world the background story as I will not allow my name to be slandered".

She goes on to claim that Def Jam has failed to support the star properly - despite huge sales of her breakthrough single Umbrella and her third album Good Girl Gone Bad - forcing Jordan to scrimp and save.
