Swift is known for inviting celebrities to dance on stage with her. During a performance of “Style” that same night, she was joined by Uzo Aduba from Orange Is the New Black and models Candice Swanepoel, Lily Aldridge, Karlie Kloss, Behati Prinsloo and Gigi Hadid. The U.S. women’s soccer team rocked out with her Friday night, fresh from the ticker tape parade celebrating their World Cup win earlier that day in Manhattan.
