"We have tried to work things out for the sake of our family, but it has become apparent that our differences at this point are irreconcilable," Bach said. "In 2011 we go our separate ways."

The couple wed in 1992 and have three children together, sons Paris, 21, and London, 14, and three-year-old daughter Sebastiana.

Bach appeared on the most recent season of VH1's Celebrity Fight Club last year.
