Before Taylor Swift arrived to ease your breakup woes, there was Alanis Morissette.
During the third of five shows at Los Angeles' Staples Center, Swift brought out the pop and breakup anthem queen to sing "You Oughta Know," fulfilling the fantasies of '90s-loving Swifties.
Swift even dubbed the tune the "greatest breakup song of all time" and credited the songwriter for inspiring her own music.

Of course, a Swift show wouldn't be complete with just one surprise guest -- so she also brought out Ellen DeGeneres, clad in her finest tutu.

Dixie Chicks singer Natalie Maines made an appearance as well, to sing "Goodbye Earl." Swift gushed about the artist, saying, "I can safely and honestly say I would not be a musician if it had not been for this artist."
"I would not have wanted to be a country artist. I wouldn’t have dreamed the things that I dreamed and I wouldn’t be standing on this stage today," she added.
I used to sing Dixie Chicks songs at every talent show. Singing 'Goodbye Earl' with Natalie tonight was unbelievable. pic.twitter.com/2r9N8T4TKq— Taylor Swift (@taylorswift13) August 25, 2015
