Actress Mayim Bialik has filed for divorce from Michael Stone, her husband of nine years. Bialik is seeking joint custody of the couple's two children.

Bialik filed the divorce petition in Los Angeles on Nov. 21, People reported. Bialik, 36, most famous for playing the title role in the television situation comedy “Blossom,” has most recently been starring as Amy Farrah Fowler on “The Big Bang Theory.” Bialik and Stone have two sons together, Miles, 7, and Fred, 4, People said.

The couple were married in August 2003, E Online reported.

Bialik, in the divorce papers obtained by TMZ, is seeking joint physical and legal custody of her two children.

Bialik takes her duties as a mother seriously, addressing the subject by creating the parenting blog Kveller and writing the book “Beyond the Sling: A Real-Life Guide to Raising Confident, Loving Children the Attachment Parenting Way.” Bialik said taking care of her two children is her “most important job” in a 2010 interview at

Bialik announced the divorce in a statement on Kveller, saying, “After much consideration and soul-searching, Michael and I have arrived at the decision to divorce due to 'Irreconcilable Differences.'” Bialik went on to say, “Divorce is terribly sad, painful, and incomprehensible for children. It is not something we have decided lightly.”

She also noted that her style of parenting played no role in the divorce. Bialik's oldest child, Miles, is homeschooled, and she practices co-sleeping, which involves sleeping with both children in the same bed as part of her attachment-parenting philosophy. Bialik is also a proponent of extended breastfeeding, having weaned her youngest son, Fred, after he was 3 years old.

This will probably be the last statement on Bialik's divorce as she contended privacy is of the utmost concern as she raises two children, saying: “The main priority for us now is to make the transition to two loving homes as smooth and painless as possible. Our sons deserve parents committed to their growth and health and that’s what we are focusing on.”
