Taylor Swift took the stage on Monday evening at the Los Angeles' Staples Center, where the 25-year-old superstar performed yet another sold-out show as part of her five-night 1989 Tour run in L.A.
As fans of the "Shake It Off" stunner know, the pop star always brings various guests on stage and last night was no exception, as she was joined by Alanis Morissette and Dixie Chicks' lead singer Natalie Maines.
"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 [Morissette] and her music. And she has written some of the most brilliant music—in particular probably inarguably the greatest breakup song of all-time," Swift told the audience (per Us Weekly), introducing the 41-year-old singer before the two belted out Morissette's epic breakup ballad "You Oughta Know."
"such a sweet celebration! thank you@taylorswift13 #1989TourLA," the Grammy-award winning rocker wrote on social media after the show.
Tonight. 'You Oughta Know'. @Alanis. I don't know how to process how amazing she was. Just absolutely magnificent. pic.twitter.com/yDhpaAszBU

Instead of her model pals, the singer was joined on stage by Ellen DeGeneres, who rocked the concert catwalk while sporting a sparkly jumpsuit (reminiscent of one of T.Swift's concert costumes) teamed with a tutu.
"When @TheEllenShow walks out in a more sparkly outfit than yours and a tutu," she wrote on Twitter with a link to an Instagram video capturing the hilarious moment.
I used to sing Dixie Chicks songs at every talent show. Singing 'Goodbye Earl' with Natalie tonight was unbelievable. pic.twitter.com/2r9N8T4TKq

Who do you think is taller? Me or Taylor Swift? #sounfair

And of course, the audience itself was also star-studded as both Jessica Alba and Kate Hudson took their kids to the concert.
The seven-time Grammy-winner will take the stage at Staples again this evening followed by her final Los Angeles show tomorrow night. Past special guests on the 1989 Tour include Julia Roberts, Karlie Kloss, Gigi Hadid, Serena Williams, Uzo Aduba, Mary J. Blige, Martha Hunt, Matt LeBlanc, Chris Rock, the U.S. Women's Soccer team, Ciara, Russell Wilson, Kobe Bryant and more.
