Gavin Rossdale and Gwen Stefani split up in August, and their divorce was finalized in October. Of course, nobody really knows what caused the relationship to dissolve, but tabloids are now reporting that Gavin Rossdale’s alleged indiscretions could’ve played a huge role.

US Weekly is reporting that Rossdale engaged in a three-year affair with the couple’s nanny, Mindy Mann.

From US Weekly:

The No Doubt frontwoman discovered explicit texts between Rossdale and the nanny — including nude photos of Mann and their plans to meet up for sex — on the family’s iPad.

“The iPad was linked to Gavin’s phone,” a family source tells Us. “One of the other nannies discovered the exchange and told Gwen.”

According to the sources, this revelation made Stefani pretty livid. Go figure.

Extra claims that Mann “has been talking non-stop about Gavin for the last year, and that she skipped town after the story broke.”

Of course, Gwen Stefani has moved on. She’s currently dating The Voice co-star Blake Shelton. After weeks of rumors, the couple finally went public with their relationship earlier this month.

“He’s a pretty rad guy, I have to say that,” Gwen Stefani said.
