Word is, the IRS is coming for Rihanna and in response, she is blaming her ex-accountants. According to RiRi, she has lost tens of millions of dollars due the faulty practices of New York-based Berdon LLP and two accountants. Rihanna’s lawyers are saying that the company’s lack of sound financial advice led to the loss of millions despite robust revenues from her “Last Girl On Earth” Tour Back in 2009.

Here’s how the AJC is reporting it:

The lawsuit alleged that the practice of paying itself commissions on revenues was not standard in the accounting and business management industry and created a clear conflict of interest.

Rihanna’s lawyers also blamed the accounting firm for an ongoing IRS audit of her tax returns, saying she was forced to spend significant resources to correct errors resulting from negligence.

Since firing the firm and its accountants in September 2010, Rihanna’s fortunes already have reversed, the lawsuit said. The “Loud” tour stretching from June 2011 to December 2011 produced a net profit equal to more than 40 percent of total tour revenues, it added.
