Following Elvira’s recent admission that Ariana Grande was her worst celebrity encounter, the Wicked star has issued a ‘sincere’ apology.

At a Knotts Berry Farm event, the Mistress of the Dark and horror hostess, real name Cassandra Peterson, recalled an experience with Grande that didn’t sit well with her.

“She came [to my show] and she brought 20 guests, so she wanted 20, 21 tickets,” she said. “We’re like, ‘Okay’, and we give her the tickets. She comes backstage and she asks if I could take pictures with all of her friends and relatives she brought.”

Peterson then claimed that she asked Grande for a photo, but was swiftly turned down: “She goes, ‘No, I don’t really do that.’ And then she left before my show started but all her relatives stayed.”

After her story went viral, Peterson posted screenshots of an article about the controversy on her Instagram account. In the comments section, Grande posted a statement in which she apologised for her actions and explained that she suffered an “anxiety attack” at the time.

“I’m so disheartened to see this,” wrote Grande. “I actually don’t even remember getting the chance to meet you because i had an anxiety attack and to my memory, left before the rest of my family.”

The ‘yes, and?’ singer clarified that the incident took place seven years ago, at a time when she was “really not great with being in public crowds or loud places”.

“But if i’m misremembering this moment, i sincerely apologize for offending you so. thank you for being so nice to my mom, she told me how lovely you were (she might have different feelings about that now but i’ll talk to her… clearly, we all have our days!) sending love always,” Grande continued.

She concluded her post: “You’ll always be our queen of halloween!”

Although Peterson didn’t respond, she seemingly accepted Grande’s apology by liking her comment.
