Actress Mayim Bialik is officially a single woman after her divorce was finalised in Los Angeles.

The Big Bang Theory star filed papers to end her nine-year marriage to Michael Stone in November (12), citing irreconcilable differences as the reason for their split, and now a U.S. judge has formally dissolved the couple's union.

The former lovers married in 2003 and are parents to two sons, Miles, seven, and Fred, four.

According to Tmz.com, Bialik was granted ownership of the family's home in Studio City, California, while Stone was awarded their three-bedroom property in nearby Sherman Oaks.
