Rihanna believes that her money was mishandled and she decided to take legal action this Thursday by suing her former accountants for alleged "tens of millions of dollars in losses, shoddy bookkeeping, a failure to recommend she trim expenses when a 2009 tour was losing money and an ongoing audit by the Internal Revenue Service," according to the Associated Press.

The Talk That Talk singer contends in the lawsuit that she believed that her former accountants took an abnormally large cut from her "Last Girl on Earth" tour in 2009, which left her scratching her head as to why the tour had seen "significant net losses" despite substantial revenue.

Rihanna and her lawyers cited her 2011 "Loud" tour's high net profits of more than 40 percent of the tour revenue as potential evidence that her former accountants weren't doing their job correctly.

The 24-year-old mega pop star hired the accountants at 16 in 2005. In addition to allegedly taking an extra chunk of her money, Rihanna claims that they frequently breached agreements, were involved in misconduct and malfeasance, and failed to implement a sufficient budget for her.

No word has been given yet as to when the legal proceedings will begin.
