A judge approved Wilde's split from documentary filmmaker Tao Ruspoli on Sept. 29 in Los Angeles. The judgment does not indicate how the former couple will divide their assets.
Wilde filed for divorce in March, two months after she and Ruspoli separated.
The pair have no children together.
The "House" actress cited irreconcilable differences in her divorce petition. Wilde starred in "Tron: Legacy" and this summer's "Cowboys & Aliens."
Ruspoli is the son of an Italian prince.
