During Saturday’s 1989 world tour stop, Swift welcomed Little Mix – Perrie Edwards, Jesy Nelson, Jade Thirlwall and Leigh-Anne Pinnock – out on stage to perform their hit single “Black Magic” with her.

“Little Mix smashed it in front of 50,000 screaming fans tonight,” Swift captioned an Instagram picture of herself onstage with the singers.

Though they didn’t sing with Swift, Roberts and Baez hit her now-famous stage runway and waved to the thousands of Swifties in attendance. The two women stayed onstage and indulged the crowd by dancing to Swift’s track “Style.”

“Tonight Joan Baez and Julia Roberts danced it out to ‘Style,'” Swift captioned a picture of the trio on Instagram. “These two women are my heroes. What an honor.”

During the concert on Saturday, Swift also took some time to dedicate her song “Never Grow Up” to her godson Leo Thames, the newborn of her close friend Jamie King.

“I wrote it when I was 18 or 19, but my friend just had a baby and she made me [his] godmother. I was holding this little baby the other night and I was just thinking differently,” she told the crowd about Leo. “You’re holding onto something that’s so innocent and so perfect and has no idea what’s coming for it with the world. The world is going to throw so many things at you as we grow up.”
