Lovato's collaboration with Morissette was her second performance of the night; the singer had previously belted out her biting, pop-rock song "Confident." She maintained the vocal ferocity and attitude as she and Morissette strutted across the AMA stage while belting out the Nineties mega-hit.
This year marks the 20th anniversary of Morissette's massive debut Jagged Little Pill. She's celebrated with a massive, collector's edition reissue that contains rare demos and a live recording of a London concert that featured members of Foo Fighters and Jane's Addiction in her backing band. While promoting the reissue, Morissette has been updating her hit "Ironic" with various late-night hosts, including a version with James Corden that included references to Tinder and Snapchat.
