Danica Mckellar Divorce -- 'Wonder Years' Star Officially Single

If you had a crush on Winnie Cooper from "The Wonder Years," now is your chance to strike ... Danica McKellar is officially divorced.

As TMZ first reported, McKellar filed for divorce from hubby Mike Verta last June. She cited irreconcilable differences. 

According to court docs obtained by TMZ, a judge made the divorce official this week and ordered the pre-nup -- which the couple signed in March 2009 -- is still valid. 

The couple has a 2-year-old son and the custody and support agreement between McKellar and Verta is laid out in the pre-nup ... which is sealed.
