It's over: Gwen Stefani has filed for divorce from Gavin Rossdale after 13 years of marriage

Gwen, 45, filed papers to end their marriage in a California court, citing irreconcilable differences as the reason for the split.

The Bush frontman, 49, is said to have filed his response at the same time, and both parties are allegedly seeking joint custody of their children.

The website claims that the No Doubt singer is not planning on providing Gavin with spousal support.

According to TMZ - who broke the news - the two stars did not sign a prenuptial agreement before tying the knot on September 14, 2002.

Per California law, this means that they are each entitled to half of what their community property.

Gwen is said to be worth around $80million, while Gavin is believed to be worth approximately $35million.

The couple have homes in Primrose Hill in London as well as Los Angeles.

The pair were last seen together celebrating the Fourth Of July at the home of Gwen's parents, along with their children.

On July 28, they were seen out separately but still wearing their wedding rings. Gavin was spotted at LAX while Gwen was pictured running errands in Sherman Oaks with the couple's three children.

Next month marks 13 years since Gwen and Gavin married in London. They held a second ceremony in Los Angeles two weeks later.

The musicians, who for the most part kept their relationship out of the public eye, started dating after meeting in 1995, when No Doubt opened for Bush on tour.

The couple's marriage was rocked in 2004 when Gavin discovered he had fathered a daughter, Daisy, from his previous relationship with British fashion designer Pearl Lowe.

Daisy - who was 14 at the time - took a DNA test after her mother revealed her suspicions that Gavin was the father.

The rocker reportedly immediately cut-off contact with both Pearl and Daisy after the paternity revelation but has since formed a relationship with his now 26-year-old fashion model daughter.

Gavin hit headlines again in 2010 when he admitted to having an 'experimental' fling - after having denied it years earlier - with cross-dressing pop singer Peter Robinson, aka Marilyn, in the 1980s.

He told Details magazine at the time: 'When you're 17, Jesus Christ, I don’t think there’s anything strange about any form of anything - you’re learning about life. It’s a part of growing up - that’s it, no more, no less.'

Peter later insisted that Gavin was the love of his life and was heartbroken after their relationship allegedly ended in 1986.

In January, Gwen teared-up while talking about her marriage in an interview on the Today show.

'If I look back on the whole thing the one thing that's been constant is that we both want the same thing,

'We both want to be married. We both want to be good parents, and so I feel really proud of what we've done together and that we don't...You're gonna get me crying, no don't, I'm going to get all emotional! But I am really proud of it.'

In an interview with Rolling Stone the same month, Gavin gushed of his wife 'Wow, it's so long. I can't remember much without [Gwen]. She's such a great person that I think she's taught me how to be a better person,'

He added: She's so successful and so good at what she does that it always keeps you in check at the house. You might come in with two of something, and she's got 12 of something. You can never get over-excited, there's something about that.'

Gwen and Gavin welcomed their third son Apollo in February 2014 and the Bush musician revealed in an interview with Howard Stern in September how his wife broke the unexpected news.

Gavin revealed: 'I got this email on the road, from Gwen, and the title was in capitals, "LOOK WHAT YOU DID TO ME NOW",' he began. 'I was like, "What is this?" My blood pressure went through the roof. And I opened the e-mail, and it was the pregnancy stick.'

He also said he knew exactly when the little one was conceived as he wasn't home that often.

'I did go home for Father's Day,' he explained. 'And that gives Father's Day a new meaning.'

In 2010 Gwen opened up about her conflicting feelings on having a third child to InStyle magazine.

'I don’t know,' the then 40-year-old star said. 'I... don’t want to spread myself so thin that I can't even be good for them.'

Before dating Gavin, Gwen previously romanced No Doubt bassist Tony Kanal but was left heartbroken when he ended their relationship in 1994.

She later penned 1996 hit Don't Speak, about the break-up, which topped the charts in numerous countries across the globe.

Meanwhile, Gwen has been busy filming the upcoming season nine of The Voice alongside fellow celebrity judges Adam Levine, Blake Shelton and Pharrell Williams.
