Taylor added a new girl to her squad and Twitter can’t handle it

If there's one celebrity who knows how to surround herself with strong women, it's Taylor Swift.

With a band of friends that already includes Lena Dunham, Lorde, Selena Gomez, Karlie Kloss, Kendall Jenner and more, over the weekend Tay added another fierce member to her squad.

After a sellout concert to 65,000 in London's Hyde Park, the singer was pictured looking cosy with none other than actress and gender equality activist Emma Watson. UK musician Lauren Aquilina shared a group photo via Twitter showing herself, Karlie Kloss, Martha Hunt and of course Taylor, with her arm around a VERY happy Emma:

"Spent tonight surrounded by badass girls and couldn't be happier about it," Lauren captured the photo. Within minutes Twitter exploded with fans trying to get their head around what has to be the ultimate cool-girl pairing:

While Emma seemed content to enjoy Taylor's show from the stands, the Blank Space singer couldn't resist getting some of her other pals to join her during the concert.

Models Cara Delevingne, Gigi Hadid and tennis star Serena Williams took to the stage along with Kendall, Martha and Karlie during Taylor's performance of Style:

What a team!

Before flying across to Dublin this morning (!!), Taylor enjoyed a spot of sightseeing yesterday with yet another gang of celebrity friends. "Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of," wrote the singer, sharing a photo of herself, her new mam Calvin Harris, Joe Jonas and Karlie posing in front of London's Tower Bridge.

Wonder if she's looking for an unofficial tour guide in Dublin, too…
