According to TMZ Gwen believed her husband Gavin had been unfaithful, which promoted the 45-year-old to file for divorce.
Sources have revealed to the website that their shock split was actually โa long time coming,โ partly due to the Bush frontmanโs extensive tour schedule.
The well-placed pal revealed to TMZ that Gwen wished her 49-year-old husband was home more often.
The source claims the situation was exacerbated when Gavin began feeling the former No Doubt member was being hypocritical as she also tours regularly.
Itโs not the first time the rock star has faced a romance bombshell.
In 2010, Gavin admitted to a five-year relationship with crossdresser Marilyn, real name Peter Robinson, in the mid-Eighties.
โIโve never wanted to appear closed about it, itโs not something Iโve talked about really because itโs always been in the glare of a tabloid world,โ Gavin told Details magazine in 2010.
Adding: โI think at the outset there was a sort of fear โ that was right at the beginning of Bush, and I didnโt want it to be part of it. It felt like a cheap shot, so I was like: โIโm not getting involved.โ When youโre 17, Jesus Christ, I donโt think thereโs anything strange about any form of anything โ youโre learning about life. Itโs a part of growing up โ thatโs it, no more, no less.โ
The relationship was first written about in George Michaelโs 1995 autobiography Take it Like a Man, however both men at the time denied it but eventually came clean.
Marilyn, now 52, confessed that he and Gavinโs relationship lasted five years and the rock star was the love of his life. โHe was just becoming successful in America. I agreed to lie against every grain of my being,โ Marilyn told In Touch Weekly in 2009.

Gwen and Gavin revealed that they are separating after filing divorce papers, but will continue to co-parent their kids.

โHe was just becoming successful in America. I agreed to lie against every grain of my being,โ Marilyn told In Touch Weekly in 2009 of his love affair with Gavin.
Itโs alleged Gavin hadnโt told Gwen about his former relationship with Marilyn until it surfaced years later.
In 2004, Gavinโs world was rocked yet again when a paternity test revealed he had fathered another child, Daisy Lowe, with UK fashion designer Pearl Lowe.
Despite the latest dramas to rock camp Stefani-Rossdale, the couple are seeking joint custody of their children and are determined to remain civil for the sake of their three sons Kingston, nine , Zuma, six, and Apollo, one.
