Is Taylor joining a new girl group?

If you're a regular on Taylor Swift's Instagram account, you've probably seen a ton of pics of her with girl group, Haim. They hang out so much (they even vacationed in Hawaii recently!), that fans wondered, 'Is Taylor dropping solo music to join a girl group?' Well, M can assure you that the answer to that question is no! "Taylor is happy being a solo singer," a source explains. But you can expect more from Taylor and Haim: Taylor announced that they're joining her on her 1989 tour for 17 dates across the U.S. So fun!
