After 13 years of marriage Gwen Stefani has filed for divorce from her husband Gavin Rossdale, TMZ reports. The singer cited irreconcilable differences in her petition, which also asks for joint custody of their three children, Kingston, 9, Zuma, 6 and Apollo, 1.

"While the two of us have come to the mutual decision that we will no longer be partners in marriage, we remain partners in parenthood and are committed to jointly raising our three sons in a happy and healthy environment," the two said in a joint statement.

Stefani hinted earlier this year to Cosmopolitan that the two have been through their share of ups and downs. "We go through so much together," she said, "it's a miracle that we could stay together this long."

Stefani is reportedly worth $80 million, while Bush frontman is estimated to be worth $35 million, which, with no prenup agreement, is likely to be divided equally between the two.
