Taylor Swift has become well-known for her famous group of girlfriends, but Elizabeth Olsen explained to James Corden why you may not be seeing her face on Taylor's friend-filled Instagram feed. When she appeared on The Late Late Show With James Corden on Thursday, Elizabeth said that she met the singer at a party soon after she'd been dancing to Taylor's songs in a ballet class. "I really love her, and earlier in my ballet class, I was doing a dance sequence to her music . . . and then she was there," she said. Although she refrained from showing Taylor any of the dance moves, she said, "I just talked at her for, like, a long time. And I think I blew it, because we didn't, like, exchange phone numbers or anything." Watch the cute clip above, then check out the sweet stories Taylor's friends share in a 1989 tour video.
