Pop star Rihanna is lashing out at her former accounts at Berdon LLP in lawsuit filed at the New York courthouse yesterday. The Barbadian singer whose real names is Robyn Fenty alleges the New York based accounting firm took exorbitant commissions from her earnings while husbanding them poorly.

Rihanna hired the firm in 2005 when she was 16 years old entrusting them with stewardship of her young fortune. She claims to have felt the Judas kiss of betrayal to the tune of tens of millions from the firm since then.

Much of the the lawsuit centers around the 2010 Last Girl On Earth Tour from which the singer alleges Berdon LLP took 22 percent of the tour's total revenues and paid Rihanna only six percent.

The singer is also facing tax woes. The Internal Revenue Service recently launched an audit of the Grammy winner’s 2008 through 2010 tax returns. In her lawsuit Rihanna's lawyers blame the accounting company for an ongoing Internal Revenue Service action. The lawsuit also alleges that the firm did not make sure she was being paid song royalties for her five previous album.

Berdon LLP has issued no public comment on the case at this time.
