Gwen Stefani and her former husband Gavin Rossdale loaned $50,000 to their nanny Mindy Mann in 2012 to help her start her own business, before Stefani found out about the affair, Radar Online reported, citing sources. While Stefani is rumored to be dating Blake Shelton, the reason for the failure of her marriage is said to be Rossdale’s affair with Mann.

“They loaned Mindy the money to launch Pint Size Kids, which is an indoor playground. Mindy didn’t plan on asking Gwen and Gavin for the money. It was Gavin who discovered the funds were needed to get the business open,” a source told Radar Online, adding that Stefani “is all about empowering other women, and thought it was a good investment.”

“But it was around the time that Pint Size Kids opened that Gavin and Mindy became romantically involved,” the source reportedly said, adding: “Gavin would often bring his kids there to take enrichment classes. Things got very intense with Gavin and Mindy very quickly.”

The source also said that Mann and Rossdale are not dating anymore, but “Pint Size Kids has been Mindy’s true love,” the source said, adding: “She is great with kids and is afraid the business will now go under because the affair with Gavin has been made public.”

A report on Saturday suggested that Stefani blamed herself for Rossdale’s affair with Mann. “At first, Gwen blamed herself when she found out about Gavin and Mindy. She was full of regret that she somehow caused Gavin to have a wandering eye, that she could have somehow prevented the affair, that she never ever should have hired someone so young and cute,” a source had said, adding: “These thoughts tormented her for a long time. The could have, would have, should haves nearly destroyed her.”

Shelton, who is rumored to be dating Stefani, divorced Miranda Lambert in July. Stefani and Rossdale got married in 2002 and confirmed their divorce this August. They have three children together.
