Ariana Grande was one of the special guests at tonight's A Very Wicked Halloween, a fifteenth anniversary TV special for the musical. It's no big secret that Ari's a bit of a theater nerd at heart, but it's not very often that we get to hear her pipes tackle Broadway standards. Unsurprisingly, she knocked it out of the park. The performance is her first televised appearance since splitting with Pete Davidson, and one of her first since dropping Sweetener. Later this week on Thursday, she'll be the focus of a BBC special performance.
