No doubt love is dead. Gwen Stefani and Gavin Rossdale have filed for divorce and join a number of celebrity couples calling it quits this summer.

Stefani cited irreconcilable differences and asked for joint custody of their three children - Kingston, 9, Zuma, 6, and Apollo, 1 - in her divorce petition, according to TMZ. Rossdale also asked for joint custody while filing simultaneously.

The musical couple ends their marriage after 13 years, but remain committed to their parental responsibilities.

"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," Stefani and Rossdale said in a joint statement to Us Weekly. "To that end, we respectfully request privacy from the media during this time.

The couple did not sign a prenuptial agreement so they will split their individual fortunes -- $80 million for Stefani and $35 million for Rossdale - half and half, according to TMZ. The No Doubt singer is denying her husband spousal support.
