Blake Shelton’s Health Is Gwen Stefani’s Priority as She Joins Him On the Road

Gwen Stefani is joining Blake Shelton on his tour — and it’s not to ward off groupies, but to keep her hungry hubby away from Velvetta dip, Cheetos, corn dogs and ice cream, sources tell GLOBE!

According to our source, the No Doubt frontwoman, 55, doesn’t like to leave the junk food-loving country crooner, 48, alone unsupervised for too long.

“she obviously misses him when he’s on tour, but the bigger reason is she wants to check up on him,” spills a source. “When she’s not there, all his healthy habits go out the window — he gorges on fried food and gets lazy about exercise.”

The 6-foot-5 Honey Bee singer has a history of packing on the pounds. Last year, it was reported that his pinthin wife shipped him off to a fat farm to slim him dow.

Popping up at some of his tour dates is Gwen’s way of monitoring his commitment to healthy habits, a source says. “When she’s around, she makes sure that Blake eats well and that he works out,” even though the God’s Country singer doesn’t always appreciate it.

“He enjoys a little space and feels the distance does them good, so he isn’t too happy about being treated like a junk-food junkie,” the source says.

But he also doesn’t push back. “He finds it claustrophobic and irritating, but he’ll do what he’s told. The reason he got Gwen in the first place was his happy wife, happy life attitude!”
