Elvira Star Cassandra Peterson Reveals ‘Least Favorite’ Celebrity Encounter Was With Ariana Grande For THIS Shady Reason!

We don’t think Ariana Grande will be getting invited to any more Elvira shows anytime soon!

Cassandra Peterson, who iconically played the Mistress of the Dark opened up about her “least favorite” celebrity encounter during a recent Q&A… And it’ll certainly leave you with THOUGHTS! While teasing the story to the crowd, the 73-year-old didn’t actually name the Yes, And? singer — but DID say the name of her “least favorite” celeb encounter rhymes with “Periana Manday.” Oof! The crowd quickly put two and two together, before Cassandra revealed:

“I’ll tell you briefly… She came and she brought 20 guests, so she wanted 21 tickets. We’re like, ‘Okay,’ so we give her the tickets and she comes backstage and she asks if I could take pictures with all of her friends and relatives she brought. I take a picture with every single one of them, I sign autographs for every single one of them. Then I say to her, ‘Can we take a photo together?’ She goes, ‘No, I don’t really do that.’”

OMG! After Cassandra just took pics with 20 of Ari’s friends and family?! BIG yikes! Cassandra added:

“And then he left before my show started. All of her relatives stayed and she took off.”

Someone else alongside her then says Ari is “playing the wrong witch” in reference to her role as Glinda the Good Witch in Wicked. Watch the full video (below):
