We have a new addition to our list of special Taylor Swift concert guests.
On Monday night in Los Angeles, Swift praised Alanis Morissette as a singer-songwriting role model, giving the artist props for being one of the first to talk so openly abut heartache in her material.
It’s something Swift certainly knows a lot about.
From there, Taylor introduced Morissette and the stars broke into a fun duet of "You Oughta Know," with those in attendance needing earmuffs for lyrics that included whether or not one’s girlfriend would "go down" on one "in a theater."
Tweeted Swift after the show:
"I don’t know how to process how amazing she was. Just absolutely magnificent."
