Taylor Swift added yet another star to her growing list of concert guest performers.
On Monday, she asked Alanis Morissette to join her onstage at the Staples Center in Los Angeles, and together the two performed Morissette's 1995 hit, "You Oughta Know."
"She defined the music of her decade. She inspired a generation of confessional female singer-songwriters who all of a sudden felt like you could actually say these raw feelings that you had; you could actually sing about your real life, you could put detail to it," Swift said while introducing Morissette.
Swift added, "And I think it's fair to say that so many of the female singer-songwriters of my generation, including myself, would not write the way that we do without her and her music. And she has written some of the most brilliant music -- in particular probably inarguably the greatest breakup song of all-time."

This year marks the 20th anniversary of Morissette's "Jagged Little Pill" album, which featured "You Oughta Know," along with the hits "Ironic" and "Hand In My Pocket." She's releasing a special anniversary version of the set this fall.
Swift, meanwhile, has asked a slew of entertainers to join her on tour this summer, including Gigi Hadid, Nick Jonas and Walk the Moon.
