Things are clearly heating up between Taylor Swift and Calvin Harris.
The superstar pair, who were named as music's highest earning couple who earned $146m in the last year, shared a romantic photo of them double dating with supermodels Gigi Hadid and Joe Jonas and Karlie Kloss on the River Thames.
Swift performed her roster of hits in Hyde Park last night before taking to the stage for two sold-out gigs at Dublin's 3Arena tonight and tomorrow.
"Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of," the Shake it Off singer captioned the sweet photo.
Harris is expected to join his girlfriend of nearly four months in Ireland, while fans are also hoping other members of her superstar squad will also join her.
Earlier this month, it was revealed that Ellie Goulding, who performed in Cork last year, pushing Calvin and Taylor to get together.
"I did play matchmaker, that's true. Calvin is a really great mate and he's so fantastic, and Taylor is such a cool person who I love. I thought, 'They're both really awesome and both really tall, they'll be brilliant together,’" Ellie laughed to British newspaper The Sun.
