Swift is about to wrap the American leg of her international jaunt, and decided to give her fans something special for her second show in Arlington, Texas on Saturday night (Oct. 7).
Sugarland's Jennifer Nettles and Kristian Bush joined Swift center stage before they plowed into the spirited kiss-off track, and the trio were clearly into every beat of the song as they danced together while belting it out.
On a trek full of star-studded cameos, Arlington got a double-whammy between the Sugarland surprise and Maren Morris' performance of "The Middle" with Swift the night before.
The Reputation tour continues in Australia when Swift returns to the stage in Perth on Oct. 19.
Watch Swift and Sugarland sing through "Babe" together below.
