Taylor Swift spent her Sunday boating on the Thames with boyfriend Calvin Harris after her sell-out show at Hyde Park the night before.

The Shake It Off singer, who performed to 65,000 fans at the British Summer Time festival on Saturday, sat with her arms around her DJ boyfriend on a trip along the river taking in the sights.

Taylor, 25, and Calvin, 31, are rumoured to have been dating since March, and have made their relationship public through Instagram.

The couple were joined on their boat ride by Taylor’s friends Karlie Kloss and Gigi Hadid, and her ex Joe Jonas.

Joe and Taylor’s brief relationship ended acrimoniously in 2008, but the two are now friends again, with Joe rumoured to be dating Gigi.

Taylor’s parents Andrea and Scott rode on the Thames Limo private luxury charter too.

Andrea was diagnosed with cancer in April, but has continued to support her daughter on her 1989 tour.

Karlie and Gigi had joined Taylor on stage the previous night, alongside Kendall Jenner, Cara Delevingne, Serena Williams and Martha Hunt, who all form part of Taylor’s ‘squad’.

And it seems American native Karlie might know a thing or two about the UK capital.

The boat snap is captioned, “Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of.”
