“I wanna punch young Blake Shelton’s face so hard,” Levine wrote alongside a black-and-white snap of Shelton from the country crooner’s high school years.
While it all appeared to be in good fun, Stefani didn’t let it slide, taking just 14 minutes to fire back with a slew of angry emojis.
“@adamlevine u r so dumb Gx,” the “Make Me Like You” singer responded.
Stefani’s fans were also quick to defend the country singer, with one retaliating with a similar, younger portrait of Levine. “@blakeshelton I wanna punch young @adamlevine 's face! And old @adamlevine 's face too. Lol ,” the fan tweeted.
