The Entourage star and the socialite/model, who dated for more than a year, have gone their separate ways, a source confirms to PEOPLE.
Hearst, 29, who’s the daughter of heiress Patty Hearst and is currently a judge alongside Naomi Campbell on Oxygen’s The Face, told Access Hollywood in March that she and Connolly, who stars in the new series Friends with Better Lives, had “met through mutual friends and Facebook.”
Connolly, 40, who’s filming the Entourage movie recently broke his leg while shooting a scene for the eagerly anticipated big-screen version of the beloved HBO show.
Reps for each have not commented.
