Mayim Bialik said in a blog post Wednesday she and her husband, Michael Stone, are divorcing after nine years.
Bialik broke the news on the parenting website Kveller.
"After much consideration and soul-searching, Michael and I have arrived at the decision to divorce due to 'Irreconcilable Differences,'" the actress wrote. "Divorce is terribly sad, painful and incomprehensible for children. It is not something we have decided lightly. ... We will be ok."
She and Stone are the parents of sons Miles, 7, and Frederick, 4.
