Police investigating after Ariana Grande ‘maliciously licks’ donuts

(CNN) — Things you probably shouldn’t do as an American pop superstar. One: Say you hate your country and the people in it.

Two — and this is really the big one: Lick donuts that aren’t yours.

Now, authorities are investigating after security footage showed singer Ariana Grande appearing to “maliciously lick” donuts in a Los Angeles shop, according a statement by the Lake Elsinore Police Department.

In the video, originally released to TMZ, the 22-year-old celebrity seems to stealthily touch donuts with her tongue, before jumping up and down laughing. Then, when an employee approaches with a tray full of donuts, the singer turns to a male companion and says loudly, “What the f*** is that? I hate Americans. I hate America.”

The singer tweeted an apology-of-sorts after the video went viral on social media.

“I am EXTREMELY proud to be an American,” she wrote. “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.”

But instead of addressing the alleged donut licking, Grande only added she felt “very upset” about the food habits of Americans and was “frustrated” by child obesity rates.

As backlash mounted, the singer posted a follow-up apology video on Thursday.

“Seeing a video of yourself behaving poorly, that you have no idea was taken, is such a rude awakening, that you don’t know what to do — I was so disgusted with myself,” she said.

“Not here to make any excuses or justify my behavior, because I can’t… I’m just here to apologize.”

Police said it would investigate the donut licking along with the Riverside County of Department of Environmental Health.

“It is not clear at this time if the affected donuts were disposed of or sold to another patron,” said a police press release.

Health officials also announced they would investigate the donut shop to see why the baked goods were left exposed to the public, a violation of local food safety codes.

Grande’s manager did not respond to CNN’s request for comment.
