Rumor has it, Gwen Stefani divorced Gavin Rossdale because he was cheating on her with Mindy Mann, a nanny for their three kids. A source told E! News on Thursday, November 12 that the "Hollaback Girl" singer learned about her ex-husband's affair by discovering sexts linked to an iPad for one of their kids.

A day after attending the 2015 Grammy Awards alone, "Gwen's suspicions were confirmed," said the source. "One of the other nannies went to get the iPad for one of the boys and found texts and photos that Mindy had sent to Gavin," the source said. "Gavin's texts were linked to the iPad and could be seen. They talked about meeting up to have sex and she sent naked photos."

"The nanny told Gwen everything," the source continued. After discovering the evidence of Gavin's affair, "[Gwen] immediately confronted Gavin and he tried to deny everything once again. He had a story that he was just flirting but this time Gwen had seen it with her own eyes and didn't believe it. She couldn't get past it and was devastated this was going on right under her nose. She asked Gavin to leave and knew the marriage was over."

A few weeks after the confrontation, Gavin moved out of their Beverly Hills home. On the other hand, Gwen "didn't want the news about the nanny to get out for the sake of her kids," the source said. The blonde beauty reportedly began to tell more of her friends about it over the past few weeks.

Nevertheless, Gwen has moved on since the split. She has found new love in fellow "The Voice" coach Blake Shelton. "Gwen is feeling the best she has felt in a long time despite all of this nanny stories circling," said a source of the 46-year-old singer. "Blake has been a huge support system to her not only at work but also on their personal time. They both have been helping each other, really."
