Ariana Grande’s casual doughnut-licking in a California store has landed her in trouble with the law. Police are now investigating the video that shows Grande and her rumored love interest Ricky Alvarez licking displayed doughnuts at the shop.

Riverside County public health officials are scrutinizing the video of the Wolfee Donuts store in Lake Elsinore, California. The store cashier, Mayra Solis, told a reporter that Grande didn't purchase any of the doughnuts she licked. "She was really rude," Solis added.

Joe Morin, owner of Wolfee Donuts, told the Press-Enterprise newspaper that he noticed Grande's doughnut-licking while checking surveillance footage from Saturday, when the singer visited the store with her friends. Morin shared the footage with the police and TMZ as he wants the singer to be charged for putting her saliva on freshly made sweets.

The video footage shows Grande licking the doughnuts twice. Her friend Alvarez also is seen licking the displayed doughnuts. Later, Alvarez and Grande kissed each other on the lips.

"What she did was wrong," Morin told the newspaper. However, the Department of Environmental Health is also investigating the store for violating California's retail food code by failing to protect its food products. "According to California Retail Food Code, all food must be protected from any type of customer contamination," Department of Environmental Health spokeswoman Dottie Merki told the newspaper. She added that if food items are “displayed without protection, customers can sneeze on, cough on or lick them."

Meanwhile, Grande also made some controversial comments during her store visit. "What ... is that? I hate Americans. I hate America,” she said when a store employee removed a tray of freshly baked doughnuts. In a statement to BuzzFeed, the “Problem” singer has since apologized for her remarks and behavior.

Grande, 22, said she is proud to be an American and added that “what I said in a private moment … was taken out of context and I am sorry for not using more discretion with my choice of words.” She also used the opportunity to highlight the cases of child obesity in U.S. and said she is upset with “how freely we as Americans eat and consume things without giving any thought to the consequences.”
