US Magazine has alleged that Gavin had a three-year relationship with his children’s nanny, an Australian woman named Mindy Mann.
Gwen reportedly discovered the affair after her husband of 13 years’ text messages synced to the family iPad.
“The iPad was linked to Gavin’s phone,” a family source tells the mag. “One of the other nannies discovered the exchange and told Gwen.”
According to the insider, naked pictures and explicit messages were revealed on the tablet.
The nanny, who Gwen considered to be like a sister, was fired. But the father of three never admitted to the affair until months later, which is said to be when the No Doubt frontwoman filed for divorce.
The well-placed friend revealed that the news, “completely devastated [Gwen], she was mortified, livid, and embarrassed.”
Us Magazine added that Gavin and the nanny’s sexual relationship lasted a full three years, even while Gwen was pregnant with their third child Apollo.
“This was done right under Gwen’s nose,” the source told the publication.
Although The Voice coach has been able to move on with new flame, country music star Blake Shelton, she did explain last month how the divorce came as a complete shock.
“Everybody knows that my life blew up last February. I’d just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life and it’s not. I don’t know what happened,” she told KIIS FM.
