Taylor Swift is currently in the middle of her 1989 world tour and, luckily for fans, each tour has brought out biggest celebrity guest stars. At her recent show on Friday in Philadelphia her “Bad Blood” co-stars Mariska Hargitay and Cara Delevingne joined her on stage.
Swift posted a picture of her performance on Instagram. It seemed that even Swift herself had a hard time containing her excitement and surprise from the sold out crowd. "Couldn't even contain my happiness because @caradelevingne and @therealmariskahargitay surprised the crowd tonight," Swift wrote in the caption.
Hargitay and Delevingne came out on stage while Swift was performing "Style." The ladies walked the stage and danced with Swift. That was not the only surprise for fans in Philadelphia, pop band Echosmith also joined Swift on stage and together they performed "Cool Kids."
This is not the first celebrity guest appearance on the '1989 World Tour.' In Detroit Martha Hunt and Gigi Hadid appeared and Imagine Dragons performed "Radioactive" with Swift on stage.
