Taylor Swift enjoyed a double date with her ex boyfriend Joe Jonas on Sunday (29.06.15).
The 25-year-old singer and new love Calvin Harris, 31, were joined by Joe, 25 and his rumoured girlfriend, 20-year-old model Gigi Hadid, for a boat trip on the River Thames in London.
As if there wasn't enough potential awkwardness, model Karlie Kloss, 22, who was romantically linked to Joe in 2011, was also on board.
However, Karlie has previously denied a romance, saying the pair are just "great friends".
Taylor and Joe dated in 2008 and he famously dumped her in a 27-second phone call. But, it appears that seven years is long enough for the 'Shake It Off' hitmaker to have gotten over it and the pair are often spotted hanging out with mutual friends.
The quintet appeared to be having a great time as they enjoyed a luxury charter around London and Taylor posted a picture on her social media pages.
The snap shows her cuddling up to Calvin as all five smile for the camera and she captioned it: "Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of."
The group were enjoying a relaxed day after Taylor wowed a sold-out 65,000 strong Hyde Park crowd on Saturday (28.06.15) at the Barclaycard British Summertime Festival.
She was joined on stage by a gaggle of gal pals including Gigi, Karlie, Kendall Jenner, Serena Williams, Cara Delevingne and Martha Hunt.
