Age-old beef between Elvira (Cassandra Peterson) and Ariana Grande has been given new life, causing the second "Wicked" -adjacent controversy in weeks.

Ariana Grande is apologizing after Cassandra Peterson, who plays horror character Elvira, recalled a bad encounter with the singer.

Cassandra Peterson, a.k.a. Elvira, is making waves on social media after a video from a recent event went viral in which Peterson recounted that Ariana Grande once brought several family members and friends to an event and asked Peterson to take photos with everyone — but declined to take a picture with Peterson.
