Ariana Grande Off the Hook In Donut-Licking Case

EXCLUSIVE

Ariana Grande won't have "donut-licker" on her criminal record ... because TMZ has learned she will not be charged with criminal mischief.  

A rep for the Riverside County Sheriff's Department tells TMZ, the owner of Wolfee Donuts does not want to press charges, so it's case closed.

The donut shop is the loser, because the incident triggered a health investigation and the shop only scored a B.
