Los Angeles: Singer Gwen Stefani has dropped "Rossdale" as her last name after her divorce was finalised. Last week, a judge approved the "Hollaback Girl" hitmaker's request to change her last name back to her maiden name Gwen Renee Stefani in the wake of her divorce from Gavin Rossdale, reports aceshowbiz.com. Although Stefani has always gone by the same stage name, she legally changed her last name after getting married to Rossdale in 2002. The 46-year-old singer filed for divorce from the 50-year-old musician in August 2015. They reached divorce settlement in April this year. Stefani is currently dating country singer Blake Shelton.
