No Doubt frontwoman Gwen Stefani reveals in an interview with Marie Claire magazine that her proudest accomplishment has nothing to do with music and everything to do with her marriage. Stefani and her husband, Bush lead singer Gavin Rossdale, recently celebrated their 10 year anniversary. The "Underneath It All" singer named her marriage as her greatest achievement, despite her successfully fronting No Doubt, rocking a solo singing career and starting her own fashion line. Gwen is clearly a romantic at heart!
