Taylor Swift, Alanis Morissette sing ‘You Oughta Know’ duet at Swift’s LA show

Taylor Swifts’s current tour, 1989, has been filled with celebrity cameos and it seems that Swift is not ready to stop surprising concert goers with a special appearance or two. Some past guests have included the World Cup-winning U.S. Women’s Soccer team,  Lorde, Jason Derulo, Little Big Town, Joan Baez, Kobe Bryant, OneRepublic, Mary J. Blige, and the list goes on and on.

Monday night at her concert at the LA Staples Center, Alanis Morissette joined Taylor Swift on stage for a duet of “You Oughta Know.”

Swift is no stranger to a powerful and condemning break up song, so it seems fitting to share the stage and belt out one of the most widely-known Morissette break up songs. Swift reportedly gave credit to Morissette as a major influence on her song writing, giving her and young female song writers the confidence to share their feelings, even in their rawest forms.

Morissette wasn’t the only celebrity to share the stage on Monday night. Swift brought out Ellen DeGeneres who lent her signature comedy to “Style,” and Natalie Maines from the Dixie Chicks joined the stage to sing country break up song “Goodbye Earl.”
