US Magazine has alleged that Gavin had a three-year relationship with his childrenโs nanny, an Australian woman named Mindy Mann.
Gwen reportedly discovered the affair after her husband of 13 yearsโ text messages synced to the family iPad.
โThe iPad was linked to Gavinโs phone,โ a family source tells the mag. โOne of the other nannies discovered the exchange and told Gwen.โ
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, โcompletely devastated [Gwen], she was mortified, livid, and embarrassed.โ
Us Magazine added that Gavin and the nannyโs sexual relationship lasted a full three years, even while Gwen was pregnant with their third child Apollo.
โThis was done right under Gwenโs nose,โ 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.
โEverybody knows that my life blew up last February. Iโd just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life and itโs not. I donโt know what happened,โ she told KIIS FM.
