It's over! Gwen Stefani files for divorce from Gavin Rossdale

One of entertainment's seemingly most solid marriages is over.

TMZ reports that Gwen Stefani has filed for divorce from Gavin Rossdale, her husband of 13 years. 

The pair released a joint statement confirming the split: "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 news comes as a surprise since there had been no rumblings of rockiness in the musical marriage. Though Gwen, 45, and Gavin, 49, haven't been photographed together since December of last year, Gwen spoke glowingly about her husband several months ago.

"If I look back on the whole thing the one thing that's been constant is that we both want the same thing," the tearful singer said on the US Today show. Watch that interview at the bottom.

Gwen and Gavin met on tour in 1995 and were married seven years later in London. She's seeking joint custody of their three children, Kingston, 9, Zuma, 6, and Apollo, 1.
