If you follow Taylor Swift on social media, you’ll already know that she’s besties with all three Haim sisters. (She just went on vacation to Maui with them last week.) So it makes sense that she’s bringing them on tour with her for a bunch dates on her massive 1989 world tour. “TOURING W/ SQUAD YESSSS,” she announced on Twitter earlier today. Check out all of the dates you can catch them together below.

The girls and I got to talking and I'm overjoyed to announce that @haimtheband will be joining The 1989 World Tour!! TOURING W/ SQUAD YESSSS
