Taylor Swift played her third of five 1989 World Tour shows at the Staples Center in Los Angeles on Monday night (Aug. 24), and one of the evening's special guests was none other than the Dixie Chicks' Natalie Maines.

The country-turned-pop superstar and one of her country idols performed the Chicks' "Goodbye Earl." The song, from the country trio's Fly album, was a Top 20 hit on both the Billboard Hot Country Songs and Hot 100 charts in 2000.

"If not for this woman and her band, I would not have known that you could be quirky, be fun, be yourself, be outspoken and brave and real," Swift said before introducing Maines. "I wouldn't have, when I was, you know, 9 years old, gotten my first CD. I wouldn't have dreamed the things that I dreamed, and I wouldn't be standing on this stage today."

Press play on the video above to watch the pair's performance of what Swift called her "go-to talent show song." She and Maines trade off singing portions of the tune, while Maines takes the lead on the chorus as Swift encourages the screaming crowd to jump along to the beat.

"My hologram just performed with Taylor Swift and says she had an amazing time!" Maines joked on Twitter after the show.

Alanis Morrisette and Ellen DeGeneres also made appearances onstage during Swift's Monday night concert, but Maines has not been the singer's only country guest throughout her tour. Sam Hunt performed "Take Your Time" with Swift at a mid-July show in Chicago, and during a June concert in Pittsburgh, Little Big Town came out to perform “Pontoon.”

The Dixie Chicks will head to Europe for a tour in 2016, and Maines has hinted that the group may launch a U.S. tour as well.
