Watch out world, there are two new members on Taylor Swift [1]'s squad. Welcome Adele [2] and J.K. Rowling [3], the unexpected but very much cherished new members of the team. On June 25, Taylor posted a photo on Instagram showing singer-songwriter Adele and author/dream maker J.K. Rowling hanging out at her Reputation tour [4] at Wembley Stadium in London.

"I'm so grateful for these women, for the words they've written and the worlds they've created through their art," Taylor wrote. "So stoked to have you at the show in London @adele and JK. Always." Fans were understandably freaking out on Twitter at the sweet post.

It's not the first time we've been blessed with celebrities joining Taylor on her tour. In addition to her famous groupies Adele and J.K. Rowling, she's had a number of other artists performing with her. Taylor's opening acts Charli XCX and Camila Cabello performed "Shake it Off" with her, followed by a performance from Selena Gomez [5], and even Robbie Williams, who stopped by for a rendition of "Angels."
