Taylor Swift surprised her Dallas fans on Oct. 6 when she brought out Sugarland to perform “Babe.”

Swift joined forces with Pat Monahan of Train to write the song for Sugarland’s latest album, Bigger. The pop singer’s vocals can also be heard on the track as backup on the chorus and bridge.

“[S]he was excited we were getting back together and reached out, and said, ‘Hey, I have a song,'” Sugarland’s Jennifer Nettles said, according to The Boot. “And that is a short list, ladies and gentleman, of people to whom she has said, ‘Hey, I have a song. Wanna sing it?’ So we said yes.”

The Oct. 6 show over the weekend marked the end of the North American leg of Swift’s Reputation Tour. Next, she’s jetting off to Australia.
