Blake Shelton may be enjoying his time with Gwen Stefani's kids, but unfortunately, their actual father isn't too pleased with what he's allowing them to do.
According to Radar Online, Gavin Rossdale was reportedly angered to learn that The Voice coach allowed 11-year-old Kingston and 9-year-old Zuma to play around with firearms on his property in Oklahoma.
While Gwen was allegedly said to be aware of what was happening, Gavin still didn't care.
"Gavin went berserk when he found out Blake let his kids use firearms on his ranch," an inside source claimed.
"He lost it with Gwen, telling her that if something happened to the boys he would never forgive her."
Apparently, Gwen was receptive to Gavin's concerns, understanding that as their father, Gavin has a right to be worried about the well being of his children.
"Gwen completely understands where Gavin is coming from," the source added.
"She wasn't happy with Blake either. As much as the kids love Blake and see him as part of the family, Gwen's made it very clear that he needs to respect these are Gavin's kids and not his."
While Blake has no kids of his own, there's been rumors going around that the couple are trying to have a baby in the near future.
Back in October, a source told Us Weekly that the two are "hyper-focused on getting pregnant" at the moment, with a wedding on the backburner.
"Blake told Gwen he does want kids of his own, and Gwen was willing to try," the source said.
"With her, Blake has the exact relationship and family life he'd hoped to have with Miranda. Gwen's everything he wants."
There's no word if this alleged gun fiasco has caused any sort of rift in their relationship.
