We love you Taylor can't wait to catch up very soon! xx Little Mix xx.”

The “Shake It Off” songstress further surprised her Santa Clara fans when she called on one of Hollywood’s greatest actresses Julia Roberts, along with folk rock singer Joan Baez on stage, E!News reported. The multi-awarded pop singer walked and danced along the stage runway, with Robert and Baez rocking alongside her.
