Rihanna allegedly blames her accountant for making her "effectively bankrupt" in 2009.
TMZ claims to have obtained the 25-year-old singer's legal documents, in which she is said to have insisted she had $US11 million ($A12.2 million) in cash at the beginning of 2009.
These files were reportedly handed in with connection to Rihanna's case against her accounting firm. She sued them for gross mismanagement in 2012.
The gossip site writes: "Rihanna says the accountant was not on the ball and she was horrified to learn at the end of the year she had $US2 million ($A2.22 million) left."
It continues to claim her expenses had doubled at the time, which left her struggling more.
Rihanna would have lost $US9 million ($A9.99 million) in the year and in the legal documents she also reportedly says her accountant gave her the thumbs up to buy a house priced at between $US7 million ($A7.77 million) and $US7.5 million ($A8.32 million). After allegedly taking their advice, she ended up selling the home with a $US2 million ($A2.22 million) loss.
In addition to these reported statements, the Bajan musician is also said to blame her accountants for not letting her know that her 2009 Last Girl on Earth Tour was also losing money.
In 2012 the firm hit back at Rihanna's lawsuit, insisting it was her own fault she lost so much money.
TMZ reported at the time that the law firm also defended the 22 per cent commission, saying it was "signed off on by (Rihanna) in an engagement letter that gave them permission to do so."
They reportedly claimed it was the pop star's "own financial action or inaction" or the work of those close to her, which resulted in the loss.
