Mayim Bialik and husband Michael Stone are to divorce after nine years together, according to TMZ.com. The couple - who have two children together - cite the usual "irreconcilable differences" as the reason for seeking to end their marriage.

Mayim, who previously starred in Blossom though is now best known for her role in The Big Bang Theory, had previously spoke of allowing her children to sleep in her bed, but told fans on her website, "The hands-on style of parenting we practice played no role in the changes that led to this decision," adding, "relationships are complicated no matter what style of parenting you choose.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."

Bialik, who is a mother to two boys, Miles, 7, and Frederick, 4, is also well known for her parenting book Beyond The Sling, in which she revealed that she still breastfeeds her 4 year-old son. It's been a pretty tough year for the family, with Mayim badly injuring herself in a car accident in Los Angeles in August. It was initially thought she would lose her thumb as a result of the crash, though assured fans that all fingers would remain intact.
