Fred Durst's Marriage -- One Month and Done

Fred Durst just filed for divorce against his wife Esther Nazarov -- and the papers say their marriage only lasted a month.

Durst filed the papers in L.A. County Superior Court on Tuesday, citing "irreconcilable differences."

In the papers, Durst says they were married from July 13 until August 25.

The docs don't say if Fred did it all for the nookie.
