If imitation is the sincerest form of flattery, Gwen Stefani's sons are her boyfriend Blake Shelton's biggest fans.

On Saturday Stefani's three sons (Kingston, 10, Zuma, 8, and Apollo, 3) drew on body art matching Shelton's forearm tattoo of deer tracks and barbed wire on their own little arms. Stefani shared the photo of the boys showing off their work on their outstretched limbs alongside Shelton's on Twitter.

Shelton admits that he regrets the ink, which he acknowledges looks more like Sugar Smacks than deer tracks. "I can't blame it on the tattoo guy, because I had been drinking," he told Access Hollywood in 2013. "I drew him this deer track and he just went to the copier and made a copy and slapped it on there."

A few months later, in an attempt to "fix" the tat, another artist added the two bands of barbed wire. Shelton says this just made the whole thing look stupider.

"Fencing in the coffee beans that I have," Shelton, 40, joked.
