Bach, 42, tells TMZ that the couple – who married in 1992 – have been separated since April.
"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," the heavy metal rocker says. "In 2011, we go our separate ways."
The couple has three children together: sons Paris,21, and London 14, and daughter Sebastiana, 3.
