“I am so disheartened to see this. In fact, I don’t even remember having the opportunity to meet you because I had an anxiety attack and, as I recall, left before the rest of my family (this was about 7 years ago and around 1920). “Back then, I really wasn’t very good at being in crowds or noisy places)…” she said. “But if I remember this moment incorrectly, I sincerely apologize for offending you.”

Grande may be referring to the period following her 2017 Manchester concert, when there was a deadly bombing that killed 22 people. The Grammy Award-winning singer has spoken openly about how traumatic the experience was for her.

“Thank you for being so kind to my mother. “She told me how nice you were (she may have different feelings now, but I’ll talk to her…sure, we all have our days!),” she continued. “You will always be our Halloween Queen!”

USA TODAY has reached out to representatives for Peterson and Grande for comment.

Peterson played the horror hostess character Elvira, Mistress of the Dark in the 1980s television show Elvira’s Macabre Movie and later in the 1988 film Elvira: Mistress of the Dark and the 2001 film Elvira’s Haunted Hills .
