Calvin Harris took Taylor Swift to the Guinness factory on Tuesday night (30.06.15). The 31-year-old DJ and 25-year-old singer - who were recently announced as the world's highest paid celebrity couple - were spotted taking a tour around the tourist attraction learning how the Black Stuff is made, following Taylor's concert in Dublin. Speaking to The Sun newspaper, a source said: "Taylor loves an impromptu trip, especially in a city she's not overly familiar with. They managed to keep themselves low profile so they weren't bothered by fans. "They looked to be really enjoying themselves surrounded by all that alcohol." Taylor and Calvin have been able to see a lot of each other this week, as they enjoyed a double date with her ex boyfriend Joe Jonas on Sunday (29.06.15). The 'Shake It Off' hitmaker and 'Feel So Close' producer 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. Despite the past, 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."
