Capaldi's most publicised relationship was with Scottish singer, Paige Turley, who rose to fame in the 2020 winter series of "Love Island". He was reported to have dated Turley during their time at college in 2015, which the Islander confirmed during her time on the reality show. Turley is still in a relationship with her fellow Islander, Finn Tapp, who she won the series with. Captioning a now-deleted post on Instagram, Capaldi addressed their relationship: "I met a lady. She was very nice. I loved her. I loved the look of her and I loved how she spoke." He continued in the post, "We dated for a year-and-a-half, then she left me. Then I wrote an album about it and I still think about it every day."
