We've only just recovered from the accusation that Ben Affleck had become a little too close to the 'help,' when along comes another, explosive revelation.

This time under the spotlight is Gavin Rossdale – the now estranged rocker spouse of Gwen Stefani.

Yes, numerous US sources are claiming that the Bush lead-singer conducted a THREE-year long affair with the couple's nanny… "right under Ms Stefani's nose," claims US Weekly specifically.

Understandably, the No Doubt star was said to be furious in the aftermath – immediately pulling the plug on her 13-year marriage.

US Weekly goes on to report that Ms Stefani, 46, became aware of her husband’s affair with their longtime nanny, Mindy Mann, back in February.

She seemingly discovered that he had sent explicit texts to Ms Mann via the family’s iPad: including naked photos and intimate plans to meet up for sex.

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

As for the rocker himself, he is said to have initially claimed that the exchange was merely a “flirtation” before admitting the three-year affair to his wife a few months later.

The 50-year-old rocker’s confession “completely devastated her,” the source added. “She was mortified, livid, and embarrassed.”

The couple has three sons: Kingston, 9, Zuma, 7, and Apollo, 20 months with the affair supposedly taking place while Gwen was pregnant with their youngest.
