Power couple outing!

Taylor Swift is across the pond in London, where she headlined the British Summertime festival in the capital's Hyde Park on Saturday, and she took time out of her busy schedule for a romantic Thames boat ride double date with boyfriend Calvin Harris and new lovebirds Gigi Hadid and Joe Jonas. T-Swizzle's bestie Karlie Kloss also joined in on the fun!

The "Bad Blood" songstress clearly doesn't have an issue with hanging out with her ex! The chart topper used to date the Jonas Brother, but now her model pal is his lady love. We guess there's bound to be some overlap in Hollywood!

These weren't the only famous peeps she was kicking it with, though! Tay Tay treated gal pal Gwyneth Paltrow and her son Moses to a photo op backstage at her concert, and the Goop queen took to Instagram to express her appreciation. "Thanks for giving me and my little man our best date night ever," the Oscar winner captioned with the below snapshot.

It's good to be friends with Swifty!
