Taylor Swift joined by ‘heroes’ Joan Baez and Julia Roberts during California gig – watch

Singer also performed with Little Mix as 1989 tour stopped off in Santa Clara

Taylor Swift invited Julia Roberts and Joan Baez on stage during a gig in California last night (August 15).

Swift’s 1989 tour stopped at Santa Clara’s Levi’s Stadium with actress Roberts and folk singer Baez becoming the latest big name guests to have been invited onto the stage by the pop star as she tours the world. They came onto the stage and danced with Swift as she performed the song ‘Style’.

“Please welcome to the stage, legendary singer/songwriter Joan Baez, and Academy Award winner Julia Roberts!” Swift told the thousands of fans gathered inside the stadium. She later posted a picture of the moment on Twitter in which she described the two women as “heroes”.
