VIDEO : Gwen Stefani Files For Divorce From Gavin Rossdale

TMZ has learned that pop icon Gwen Stefani has filed for divorce from her husband Gavin Rossdale. The singer cites irreconcilable differences in her divorce petition, which seeks to end their 13-year-marriage. Gwen, who's represented by attorney Scott Weston , is asking for joint custody of the couple's 3 children -- 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo. While sources say there was no pre-nuptial agreement, Gwen still checked the box on the form to deny Gavin any spousal support.
