Taylor Swift is currently on the U.K. leg of her "1989" world tour, and the singer appears to have been having the time of her life this week. Her friends Karlie Kloss, Serena Williams, Kendall Jenner, Cara Delevingne, Martha Hunt, and Gigi Hadid joined her onstage at her London concert in Hyde Park on Saturday, June 27. There was even more celebration on social media when a picture featuring "Harry Potter" star Emma Watson posing with Swift and her friends circulated online. 

On Sunday, the "Style" singer took a breather from her busy schedule to enjoy a sunset outing with her boyfriend, Calvin Harris, along with Hadid, Joe Jonas, and Kloss. The group went on a romantic boat ride on the river Thames, and Swift shared a snap of their fun excursion via Instagram, Twitter, and Tumblr on the same day. 

Swift and Harris, who wrapped their arms around each other, looked to be double dating with rumored new couple Hadid and Jonas, who sat close to each other in the photo. Kloss, grinning widely for the camera, didn't seem to mind being the fifth wheel to her friends. 

"Little known fact: Karlie is secretly an unofficial historian/ London tour guide. Kind of," the "Shake it Off" singer captioned the photo. 

The Daily Mail reports that Swift's parents, Andrea and Scott Swift, were also on the boat but they stood in front with the captain. 

The shot shows that Swift does not have any bad blood with Jonas, whom she dated back in 2008. Earlier this month, the singer also dined with Jonas and Hadid in Los Angeles. 

Swift and Harris have been linked earlier this year, but the couple appeared to have confirmed their romance in an Instagram snap earlier this month showing the two of them riding an inflatable swan in a pool. On Friday, Swift and Harris were crowned 2015's Highest Paid Couple by Forbes Magazine, knocking Beyonce and Jay Z off the top spot. The duo reportedly earned a combined $146 million last year, compared to Beyonce and Jay Z's $110.5 million.
