Taylor Swift and Calvin Harris take a star-studded boat ride with Joe Jonas, Gigi Hadid and Karlie Kloss

Taylor Swift has been totally making the most of her time in London by going on a cosy boat trip with boyfriend Calvin Harris.

But instead of making it a romantic excursion for two, the couple were joined by a group of their celeb friends – including Taylor’s rumoured ex-boyfriend Joe Jonas. Um, awkward.

Yep, 25-year-old Tay happily posed for a photo with Calvin, Joe and her model mates Gigi Hadid and Karlie Kloss as they went sightseeing along the River Thames and shared it with Instagram fans.

‘Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of,’ the Bad Blood singer jokingly captioned the snap.

Taylor was believed to have dated Joe, 25, back in 2008 when they were still teenagers. Things didn’t seem to end well between them either, as Taylor memorably claimed to Ellen DeGeneres that Joe dumped her in a 27-second phone call. Ouch!

They’ve clearly patched things up though and were happy to hang out with their mutual friends last night. In fact Joe has been romantically linked to Taylor’s pal Gigi, 20, and they certainly looked close as they sat together on the boat.

Meanwhile Taylor and Calvin, 31, appeared more loved-up than ever during the outing. The cute twosome smiled as Taylor wrapped her arms around the DJ and smiled for the camera.

With all that love in the air, we kind of feel sorry for Karlie playing gooseberry up front…

The outing came after Taylor played a huge gig at London’s Hyde Park on Saturday night and wowed the crowds by bringing out her A-list pals.

Joining the Shake It Off star on stage were (deep breath) Kendall Jenner, Cara Delevingne, Gigi Hadid, Karlie Kloss, Martha Hunt and Serena Williams for a catwalk-themed segment of the concert.

Oh to be in that circle of friends…

Did Taylor Swift just admit to the world that she’s ‘in love’ with Calvin Harris?
