The guest lists at stops along Taylor Swift's 1989 World Tour have read like a who's who of Hollywood. For her New York show, she brought the entire "Bad Blood" squad to the stage, including Lena Dunham, Lily Aldridge, Hailee Steinfeld, and Gigi Hadid. In Los Angeles, she invited Mary J. Blige and Uzo Aduba on Saturday, and Alanis Morissette and Ellen DeGeneres on Monday. But one of her special guests might top them all: boyfriend Calvin Harris. Harris was spotted in attendance at her sold-out show at L.A.'s Staples Center Monday night. One attendee filmed the video below, in which Taylor can be seen mouthing the words "I love you" to the crowd. So, was she singling out Harris in front of thousands of concertgoers? Or was she simply showing her fans some love? Our inner romantics would like to think the former.
