It's War! Gavin Rossdale SLAMS Blake Shelton For Spending Time With Gwen Stefani's Boys — The Shocking New Report That's Stunned Fans

Gavin Rossdale doesn't want to share his kids with Blake Shelton!

The 50-year-old rocker is wary of the time his 46-year-old ex-wife Gwen Stefani and their three kids, Kingston, 10, Zuma, 7, and Apollo, 2, have been spending with the 40-year-old country star — and if he has his way in court, his boys won't see Blake again!

"He's concerned because the boys seem to be picking up bad habits," an insider revealed to In Touch. "He's complained that the boys are going to bed with no baths, staying up late and eating junk food."

"Gavin knows going to court would be a huge gamble, and Gwen hasn't deprived him of custodial time [that's laid out in] the agreement," the source added. "But he wants to have a say about when and where the kids go when he isn't with them."

However, the insider noted that the boys love spending time with Blake at his Oklahoma ranch, as "they go hunting and fishing and Blake drives them around in dune buggies. Kingston has been riding a dirt bike. It's a huge playground for the kids! They can't wait to go back."

As Star readers know, this isn't the first time the boys have been in the middle of their parents' divorce.

The No Doubt singer previously called sharing her kids with Gavin "unjust" and banned him from Apollo's birthday party.
