Stefani requested joint custody for the couple's three kids: 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo. Rossdale filed a response concurrently and is also asking for joint custody.

"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 press. "To that end, we respectfully request privacy from the media during this time."
