Taylor Swift's posse of famous friends continues to expand, and we're getting kind of jealous! Headlining the British Summer Time Hyde Park concert in London on Saturday, June 27, Swift brought mega star power to the stage when Kendall Jenner, Serena Williams, Karlie Kloss, Gigi Hadid, and Cara Delevingne crashed her "Style" performance, but the celeb spotting didn’t stop there.

Backstage after the show, the "Blank Space" singer, 25, hung out with none other than Gwyneth Paltrow, who attended the concert with her 9-year-old son Moses Martin. "Thanks for giving me and my little man our best date night ever," an excited Paltrow, 42, shared when Instagramming a pic of the trio on June 29.

Paltrow and Swift’s friendship goes way back. In 2010, the actress hosted a private dinner party for Swift and then-boyfriend Jake Gyllenhaal. After Paltrow's introduction, the duo dated for two months before Gyllenhaal pulled the plug.

Currently traveling the world on her 1989 tour, Swift had more excitement this weekend when Forbes crowned her and boyfriend Calvin Harris as 2015's highest-paid couple. Tayvin, as dedicated fans call them, cashed in a collective $146 million in the last 12 months to dethrone Beyonce and Jay Z, who fell to second place having earned $110.5 million.

Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of.

Swift and her Scottish boyfriend made the most of their off time this weekend in London, touring the city on a double date with Hadid and Joe Jonas. Along for the ride? Swift's BFF Kloss. "Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of," Swift wrote when sharing an Instagram snap of the five of them smiling at the camera.
