Mindy Mann, the nanny who was reportedly involved in a three-year affair with Gwen Stefani's ex-husband, Gavin Rossdale, has just been exposed as a Stefani "copycat," at least according to recent reports.

Although Mann's Instagram account is marked private, her profile photo features a woman with white-blonde hair, sporting a bandana tied around her head, much like the bandana Stefani has worn in the past -- and that's not all.

In the bio section of Mann's account, a messge reads, "Just follow your heart," and a Gmail email address is given.

On November 11, the Daily Mail uncovered a number of Mann's Facebook photos.

"Photographs posted on Facebook by Mindy Mann, the nanny alleged to have had a three-year affair with Bush Rocker Gavin Rossdale, show the 20-something in a series of poses that are creepily similar to her superstar boss Gwen Stefani," the site explained, "Wearing lookalike black rimmed glasses, a bandana in her platinum hair and striking a pose with the rock couple's seven-year-old son Zuma, the Australian nanny has created eerie matches of photos of [Stefani]."

In the new issue of Us Weekly, which exposes Mann's rumored affair with Rossdale, a source hinted at a possible Stefani obsession.

"If Gwen would eat something or do a workout or get a new handbag, Mindy would do the same thing. Gwen thought it was weird," the source noted.
