Ariana Grande will not appear in "American Horror Story" Season 13 due to scheduling conflicts related to her "Eternal Sunshine" tour, according to Page Six. The 33-year-old singer was originally announced as a cast member in October but could not accommodate the filming schedule after production dates changed. Sources told Deadline that Grande has not filmed anything for the forthcoming installment. Grande was expected to join a star-studded cast including Sarah Paulson, Evan Peters, Angela Bassett, Kathy Bates, Jessica Lange, and others. The pop star previously worked with series creator Ryan Murphy on "Scream Queens" in 2015. Grande is currently busy with her tour, which recently had several dates rescheduled due to production issues, including shows at New York's Barclays Center and Boston's TD Garden.
