Taylor Swift Hangs Out With Gwyneth Paltrow and Her Son in London

Gwyneth Paltrow gave Taylor Swift a sweet shout-out on social media after she and her son, Moses, attended the star's concert in London over the weekend. Gwyneth posted a picture of the cute trio on Instagram, writing, "#taylorswift thanks for giving me and my little man our best date night ever. #hydepark." In the photo, Taylor has her arms around Gwyneth and nine-year-old Moses, who's flashing a big grin for the camera.

Gwyneth wasn't the only star at Taylor's London show, as she was joined on stage by some of her famous BFFs. Kendall Jenner, Gigi Hadid, Karlie Kloss, Cara Delevingne, Martha Hunt, and Serena Williams turned the stage into a runway when Taylor performed "Style." Meanwhile, Taylor also linked up with Emma Watson backstage, both stars looking more than a little excited to be hanging out. The good times kept coming for Taylor, too; in a picture posted early Monday morning, she cuddled up to boyfriend Calvin Harris during a boat ride with Karlie Kloss and rumored couple Gigi Hadid and Joe Jonas.
