April 30, 2026 AceShowbiz - Olivia Rodrigo is set to host and serve as the musical guest on this week's episode of Saturday Night Live, and the promotional clip promises an entertaining twist. The promo features a devil character dressed in Prada, but it's not the usual suspects like Meryl Streep or Anna Wintour. Instead, the devil is portrayed by James Austin Johnson, who delivers a spot-on impression that even outdoes Streep's iconic role.
