Gwen Stefani and her husband Gavin Rossdale are divorcing after nearly 13 years of marriage.

Gwen Stefani has filed her petition for divorce on August 3 at Los Angeles Superior Court citing irreconcilable differences.

She married the Bush singer at a church in London’s Covent Garden in September 2002 and they have three sons together.

Gwen Stefani and Gavin Rossdale say they want joint custody of Kingston, 9, Zuma, 6, and Apollo, who was born last February.

In a statement the former couple said they were committed to raising their children together.

The singers said: “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.

“To that end, we respectfully request privacy from the media during this time.”

Gwen Stefani, 45, is a coach on The Voice.

The singer and her 49-year-old husband worked together on The Voice in 2013, but she later admitted it had been “awkward”.

“We’ve only collaborated on making babies,” she admitted.

Gwen Stefani is also a successful designer and launched her own fashion label L.A.M.B. in 2003.

She posted a picture online a week ago in which she appeared to be on holiday in Montana.

Gwen Stefani wrote: “Wow #Montana u r so beautiful #favoritevacaever #neverwanttogohome.”

Gavin Rossdale tweeted his 170,000 followers on July 29, saying: “Bye bye London. Flying home.”

No date of separation was listed in the Los Angeles court filings.
