Gavin Rossdale steps out with his and Gwen Stefani's kids…and their new nanny

Gavin Rossdale's 13-year marriage to Gwen Stefani is said to have ended after he cheated with Aussie nanny and Gwen lookalike Mindy Mann.

But the singer appears to have hired a new nanny…and she looks nothing like his ex-wife.

The family's new employee, who accompanied Gavin, 50, on a day out in Beverly Hills with his sons Apollo, 20 months, Zuma, seven, and Kingston, nine, has been spotted out with the family on a few occasions this week.

But according to TMZ, she has been working for them since Apollo's birth and could have been selected by either Gwen or Gavin.

As for Mindy, who was allegedly fired after her rumoured three-year affair with Gavin ended in February 2014, she's said to be laying low.

"Gavin hasn't spoken about her," a source close to Gavin told E! News. "I don't think they've spoken in a while."

The rocker, who has not commented publicly on his split with Gwen, is said to be "taking the high road" with the divorce, according to E! News.

Meanwhile, Gwen, 46, who is currently dating her fellow The Voice judge Blake Shelton, recently admitted that the end of her marriage to the Bush frontman was "unexpected".

According to Us Weekly, the affair with their nanny was uncovered when another of the nannies discovered nude photos and explicit texts.

Gwen is said to have confronted Gavin about the affair in February, and they both filed for divorce in August.
