Another day, another addition to Taylor Swift's all-star concert squad!
The pop singer welcomed Julia Roberts and renowned folk artist Joan Baez to the stage on Saturday night, and this time Taylor was the one who was star-struck.
"Tonight Joan Baez and Julia Roberts danced it out to 'Style'. These two women are my heroes. What an honor," she said of the two legends, captioning an Instagram shot of Julia and Joan in front of the sold-out crowd at Levi's Stadium in Santa Clara, Calif.
