Kirke met Australian singer-songwriter Alex Cameron in 2017 when Cameron was producing his album, "Forced Witness." The singer told The Fader, "She'd heard a song of mine and reached out because she wanted to make a music video for Stranger's Kiss.'" After their artistic collaboration on Cameron's music video (which Kirke directed), he told the outlet that the pair spent more time together and developed feelings outside of their professional relationship. Shortly after the two started dating, Cameron moved in with Kirke and her children in New York City, according to The Guardian.
After nearly five years of dating, the pair are still going strong and continue to work together, with Kirke directing the music video for Cameron's song "Best Life" off of his March 2022 album, "Oxy Music." Discussing their relationship, the singer revealed to Range in March 2022, "[Jemima's] whip-smart, incredibly intelligent, and her taste is just the finest and best in the world. Anyone I've ever come across has never even come close to Jemima in terms of her ideas. She's just amazing."
