Jessica Simpson chats with ET backstage at the ‘American Idol’ season 23 finale, which aired live on ABC and is now streaming on Hulu. The singer marked her TV performance return on Sunday night, her first broadcast performance in 15 years, to duet ‘These Boots Are Made for Walking’ with ‘Idol’ hopeful Josh King, and her new single, ‘Blame Me.’ She reflects on her new, independent music chapter and upcoming guest spot on Kim Kardashian’s legal drama, ‘All’s Fair,’ coming this fall to Hulu.
