Unbreak her . . . bank account?

TMZ reports that Toni Braxton is in big trouble after fraudulently wiring her estranged husband more than $50,000.

Musician Keri Lewis -- who separated from his wife of a decade in 2009 -- supposedly received the money just before Braxton's 2010 bankruptcy filing. The bankruptcy trustees are currently suing Lewis in order to recover the $53,490 sum, which they posit the singer transferred in order to avoid having to use it to pay back her creditors.

Two years ago, Braxton was allegedly somewhere between $10 million and $50 million in debt, prompting her to file bankruptcy.

A rep for the "Unbreak My Heart" crooner, 45, denies any wrongdoing on her part.

"All of the payments made to Lewis prior to Toni's bankruptcy filing were appropriate transfers for reasonable and necessary personal and business expenses in the ordinary course of her business," her rep told TMZ, adding that Braxton is happy to provide whatever information necessary in order to clear her and her spouse's names.
