"I'm so grateful for these women".
The photos, which were posted on Instagram, show the singer cosying up with the ‘Hello’ singer and Harry Potter creator individually.
“I’m so grateful for these women, for the words they’ve written and the worlds they’ve created through their art… so stoked to have you at the show in London @adele and J.K”.
But while there was a lot of love for Adele’s photo with Taylor – it was the unexpected crossover of Swifties and Potterheads that got fans excited.
One wrote on Twitter: “Seeing my favorite author @jk_rowling and favorite musician @taylorswift13 in a picture together makes my heart happier than you can possibly imagine on this Monday morning”.
Another said: “taylor swift and j.k. rowling in a selfie together is such an unexpected collision of my brands that i am CLUTCHING my hufflepuff heart”.
Although the superstar pairing took place back stage, there was some epic team ups onstage too.
On Saturday night, Robbie Williams unexpectedly joined Taylor to sing ‘Angels’, prompting a huge reaction from the crowd.
Only a day before, she was joined by former One Direction star Niall Horan, who sang ‘Slow Hands’ with Taylor.
She was also joined at the shows by support acts Charli XCX and Camilla Cabello – who duetted with the star after joining forces during previous shows.
