So Taylor Swift Could Be the 6th Member of Fifth Harmony, No Problem

We knew eventually Taylor Swift would bring Fifth Harmony on stage as guests at one of her 1989 world tour concerts — don't forget, Camila Cabello is part of Taylor's glamorous squad. But even though we were expecting the collaboration, when Taylor and the band hit the stage for her second concert in Santa Clara, CA, we were blown away. Taylor, in one of Camila's outfits, not only sang "Worth It" with the band but also danced to the sexy choreography, totally going above and beyond our wildest dreams. If you lived under a rock and didn't know who Taylor was, you would have believed she was the sixth member of the girl group.
