No doubt Rihanna "can't remember to forget" the mistakes she says her accountants made — which resulted in the Unapologetic singer nearing bankruptcy in 2009.

She might be singing "All I see is signs / All I see is dollar signs" now — but in her gross mismanagement lawsuit against accounting firm Berdon LLP, she says she found herself "effectively bankrupt" four years ago.

In legal documents obtained by TMZ, RiRi claims she had $11 million at the beginning of 2009 and only $2 million by the end of the year — and that she saw her expenses double.

How did she drop all those dolla bills? She says that her accountants gave her the go-ahead to sink $7 million into a Beverly Hills house she ended up selling at a $2.4 million loss two years later.

She also claims that her accountant never told her that her Last Girl on Earth tour was losing money.

Finally, Rihanna alleges that the firm's commission was a staggering 22 percent. Berdon, for its part, says that she signed off on the commission.

These days, however, the Barbadian pop star is riding high. Her current estimated net worth of $43 million can surely buy a few "Diamonds."
