Radar previously reported the singer had become wary of her husband's relationship with the nanny prior to their separation and had subsequently fired the caretaker over rumors she was having an affair with Gavin.

“The nanny was very attractive, but in the beginning, Gwen trusted her and treated her as a younger sister/best friend," the insider revealed, adding The Voice star's children now "aren’t allowed to be around their ex-nanny [as] it would be just so confusing for them.”
