Gwen Stefani’s Ex Gavin Not Happy Blake Shelton Let His Sons Fire Guns — Report
But who wasn't too thrilled about it? The boys' father and Gwen's ex-husband, Gavin Rossdale.
The rocker was not angry that his kids were with their (probably) future step-dad for the holiday weekend, but rather that Blake allowed his and Gwen's two oldest sons — Kingston, 11, and Zuma, 9 — to fire guns while they were there.
"Gavin went berserk when he found out Blake let his kids use firearms on his ranch," an inside source told Radar.
"He lost it with Gwen, telling her that if something happened to the boys he would never forgive her."
While we hardly believe the "Hollaback Girl" would ever put her kids in harm's way, she apparently agreed with her ex that the guns weren't safe, and told Blake that he "needs to respect these are Gavin's kids and not his."
The source insists the Bush frontman is also getting increasingly angry that his boys are getting so close with the country star.
The kids did make cameos in Blake's new music video, "I'll Name the Dogs," after all!
Zuma and 3-year-old brother Apollo especially love Blake, even rockin' camoflauge like him and sometimes calling him "daddy!"
But exes be damned — The Voice couple is still going strong two years into their romance.
They proved they're still adorable AF while performing their festive duet, "Make It Feel Like Christmas," on their hit NBC show.
"She was so excited," the Sexiest Man Alive gushed of the song his lady wrote.
"I love seeing her that happy. She's so happy when she’s writing and just hearing that in her voice and how into it she was, I just couldn’t stop thinking about (it) so I got my guitar out and thought, 'I wonder if I could help her in some way?'"
"I couldn't have been more honored or more proud to be on one of her records."
Rumor has it the musically-inclined duo are thinking about having a baby before they walk down the aisle, so here's to hoping we'll get more sappy love songs — and lullabyes — from these two in 2018!
