R&B star Rihanna has apparently fired her business manager, Patricia Williams, after discovering that she's lost almost all of her income.

The singer and her management company, Rebel One, were reportedly told by Williams that Rihanna was only worth $20,000.

Rihanna is said to have accused Williams of stealing her money, a claim which the business manager denied in an interview with Blackarazzi.

“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?” Williams said.

“I showed her all the paperwork and tried to explain to her the circumstances but she wouldn’t listen.”

Williams said that she felt compelled “not to allow my name to be slandered” and claimed that the singer's biggest hit 'Umbrella' had been inadequately funded by her label Def Jam.

She added that Rihanna's manager Marc Jordan, owner of Rebel One Management, was to blame for the crisis.

“I don’t want to disrespect Marc’s name. He is a fantastic manager and genuinely believes in Rihanna.

"But he uses her money to fund her future projects because he believes he can break her in the world-marke,” she said.
