Here we go again… “Us Weekly says that Gwen Stefani and Gavin Rossdale broke up over the NANNY. Gwen supposedly found out back in February that Gavin had been hooking up with her for three years! Her name is Mindy Mann, and she’d been exchanging texts and nude pictures with Gavin. Another nanny found out and told Gwen about it. Mindy was fired, and word is Gavin spent months saying it was just “flirtation”. He finally fessed up, and that’s when she decided to leave him.
