Taylor Swift Rocks Third L.A. Show, Brings Out Surprise Guests Alanis Morissette & Ellen DeGeneres!

So far, Taylor Swift’s Los Angeles shows have been a star-studded spectacle, with everyone from Kobe Bryant to Mary J. Blige joining the superstar on stage. Monday night’s show – her third in her five-night stop – was no less impressive, as the singer brought even more famous friends to the brights lights of the Staples Center stage.

Dixie Chicks singer Natalie Maines was Swift’s first onstage guest and the singer gushed about the country group’s influence on her early music career, saying they taught her that it’s OK to be "quirky."

"I can safely and honestly say I would not be a musician if it had not been for this artist," Swift told the crowd when introducing Maines. "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."

Maines joined Swift for a duet of the country group’s hit "Goodbye Earl," which the 25-year-old singer revealed as her "go-to talent show song."

That wasn’t all! Swift introduced her next guest with these words of praise, "The person I’m about to bring out defined the music of her decade. She defined the generation of female songwriters. She taught us you could get really, really mad if you wanted to. It’s fair to say that many of the female songwriters would not write the way we do without her music."

And that was when Alanis Morissette made her grand entrance before diving into a stellar performance of her 1995 hit, "You Oughta Know," to the delight of the crowd!
