Is there any celebrity that Taylor Swift ISN'T friends with? Moreover, is there any celebrity who is brave enough to turn her down when she requests they join her on stage?
She played five nights at the Staples Center in Los Angeles over the weekend and on the third night, she brought none other than Alanis Morissette out to duet on 'You Oughta Know'; Morissette is celebrating 20 years of the album that that song is taken from, 'Jagged Little Pill'.
During the same gig, she also brought out Natalie Maines of The Dixie Chicks to sing on 'Goodbye Earl', while Ellen DeGeneres made an appearance during 'Style'.
