Jake Gyllenhaal typically keeps his love life out of the spotlight, but he's given small glimpses into his relationship with girlfriend Jeanne Cadieu. Gyllenhaal and Cadieu started dating in 2018, making their red carpet debut as a couple three years later at a screening of The Lost Daughter. The film was directed, written and produced by Jake's older sister, Maggie Gyllenhaal. While the pair have had their fair share of public outings, Jake has been open about the fact that he and Cadieu prefer to keep their romance low-key.
