The 46-year-old "Misery" singer filed legal documents in a Los Angeles Superior Court last month to officially drop Rossdale from her last name. According to the documents obtained by ET, the pop star requests that her name be restored to Gwen Renée Stefani.
Although the No Doubt front woman has always gone by the same stage name, she legally changed her name to Gwen Stefani Rossdale after marrying Gavin Rossdale in 2002. The former couple, who share three children -- 10-year-old Kingston, 7-year-old Zuma, and 2-year-old Apollo -- finalized their divorce last year.
Stefani has since moved on with Blake Shelton, whose marriage to Miranda Lambert also ended in 2015.

In a recent interview with Chelsea Handler, Shelton opened up about meeting Stefani during a rocky time in both of their personal lives. "My marriage fell apart," explained the 40-year-old country star. "To find out she's going through the exact same thing at the same time ... All this has to be meant to happen."
