The 46-year-old Stefani reportedly went for divorce after she came to know that Rossdale was cheating on her. The 50-year-old Bush frontman allegedly had a decade-long affair with Mindy Mann, nanny to the couple's three children.

With headphones on and dressed casually, Stefani visited "The Voice" studio a few hours before Rossdale was seen at a Hollywood office. Interestingly, Rossdale was spotted wearing his wedding band.

Stefani looked great in a bright neon pink sweater and wearing mirrored sunglasses on a smiling face. She reportedly is in a relationship with Blake Shelton and was aware of her husband's infidelity prior to her divorce filing.

It was said that Rossdale cheated on Stefani with the nanny when the actress was in the hospital following the birth of their youngest son, Daily Mail has learned. This played a role in their separation and divorce filing.

However, the former couple is fiercely protective of their children. They did not go public or react to any news on their split fearing negative impact on their young sons.

A source close to the couple told People that Stefani kept the news about her husband's affair with the nanny a secret to ensure that it did not impact her three sons while Rossdale is equally concerned about the kids and ready to make all possible effort to keep things as normal as possible,

The separation came 13 years after the former couple tied the knot. In the absence of any prenuptial agreement, both have equal share in the properties jointly owned, including houses in London and Los Angeles. The actress is worth $80 million while the English musician owns property estimated to be around $35million.
