Broadway star Jarrod Spector from the musical The Cher Show called out Kanye West on Twitter after seeing the rapper on his cellphone during the show’s opening night Monday. “Hey @kanyewest so cool that you’re here at @TheCherShow!” tweeted Spector, who plays Sonny Bono in the production. “If you look up from your cell phone you’ll see we’re doing a show up here. It’s opening night. Kind of a big deal for us. Thanks so much.” West, who attended the performance with his wife Kim Kardashian West, later apologized on Twitter for his “lack of etiquette.” “To Cher and the Cher show team the dynamics of Cher and Sonny’s relationship made Kim and I grab each other’s hand and sing ‘I got you babe.’ Please pardon my lack of etiquette. We have so much appreciation for the energy you guys put into making this master piece.”
