Gwen Stefani and her husband, Gavin Rossdale, parted ways last August after he allegedly admitted to cheating on her with their former nanny, Mindy Mann. However, despite his rumored infidelity, Rossdale reportedly made out quite well.

According to a new report, Rossdale not only received joint custody of his and Stefani's twins, he also got half of her hard earned money--and an additional cash payout--even though he was believed to be harboring money in off-shore accounts.

"Over the course of their 13 year marriage, Gavin was stashing cash in off-shore bank accounts, ensuring that Gwen wouldn’t be able to touch the assets if they split," OK! Magazine reported on Friday.

“Gwen is devastated” a source told the magazine. “She’s kicking herself for not being more aware of what was going on with their finances. She had no idea that Gavin was squirreling money away.”

Because California is a non-fault state when it comes to divorce, Rossdale's alleged infidelity, had it been admitted at any point, wouldn't have made any difference in regard to the division of their assets.

Although Stefani and Rossdale never addressed his alleged affair with the nanny publicly, she did admit to Ryan Seacrest that something traumatic had happened to her in February of last year, which is when Us Weekly claimed she learned of his and Mann's inappropriate conduct.
