Typical Taylor. Super-supportive girlfriend Taylor Swift attended Coachella this weekend ? with several members of her squad in tow ? to watch Calvin Harris close out the music festival. The world expected Swift's usual dance moves, but when Rihanna surprised them by appearing during Harris' set, Swift reached peak panic. The singer Instagrammed the experience, where pals like Lorde, Martha Hunt and Camila Cabello can briefly be spotted dancing/screaming along to "We found love."
