This may seem like a long time coming.
For years there have been rumors of Rossdale cheating on Gwenny-Gwen-Gwen and it seems like this was the straw that broke the camel's back.
Who's crazy to cheat on this baddie? Obviously, this ridiculous guy.
"Gwen cites irreconcilable differences in her divorce petition, which seeks to end their 13-year-marriage.
Gwen, who's repped by attorney Scott Weston, is asking for joint custody of the couple's 3 kids -- 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo. Gavin, who's repped by disso-queen Laura Wasser, filed his response at the same time, and he's also asking for joint custody. It's clear the petition and response were orchestrated to be filed simultaneously.
Sources tell TMZ there is no prenup, so the 50/50 California community property laws kick in. 45-year-old Gwen is worth a reported $80 million, and 49-year-old Gavin's worth an estimated $35 million. Given the length of the marriage, that will probably all go into one pot before it's divided.
We're told Gwen complained about Gavin being away from home too much, touring with his band Bush from December 2014 through March 2015. One source says Gwen put pressure on him to stop touring and stay home. For his part, he felt it she was hypocritical because she was on the road too.
Our sources say Gavin is a very good father, so both sides are seeking a joint custody arrangement. "
The couple confirmed the news by releasing the statement:
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.
