Jason Ralph, husband of actress Rachel Brosnahan, sparked online speculation by liking an Instagram comment suggesting his wife is romantically involved with her ‘Superman’ co-star David Corenswet. The social media interaction occurred amid persistent rumors about Brosnahan and Corenswet’s off-screen relationship, prompting mixed reactions from fans and leading Ralph to disable comments on his posts.
Rachel Brosnahan, best known for her Emmy-winning role in ‘The Marvelous Mrs. Maisel,’ stars as Lois Lane opposite David Corenswet’s Superman in director James Gunn’s 2025 superhero film. Her husband Jason Ralph, an actor recognized for his work in ‘The Magicians,’ has been married to Brosnahan since approximately 2018. The couple met while filming the 2013 indie movie ‘I’m Obsessed With You’ and have maintained a relatively private relationship.
The incident occurred on August 14, 2025, when Ralph engaged with a comment under his June Instagram post. The comment accused Brosnahan of infidelity and suggested Ralph was being disrespected, stating: ‘It’s genuinely sad to see your career being tucked out to be remembered as a cuckold because your wife couldn’t handle herself with her co-actor.’ After liking the remark, Ralph disabled comments on all his Instagram posts.
Speculation about Brosnahan and Corenswet’s relationship intensified after a viral video from the ‘Superman’ set showed them continuing to kiss after a scene concluded. Both actors are married—Corenswet to Julia Warner since 2023, with whom he shares a child—but this hasn’t quelled rumors about their on-set chemistry. During the film’s July press tour, Brosnahan described their ‘impactful’ chemistry read and subsequent bonding over breakfast.
Reactions to Ralph’s social media activity have been polarized. Some critics called his behavior ‘weird’ and questioned why a working actor would engage with such comments, while defenders argued he might be mockingly dismissing the rumor or demonstrating security in his marriage. The incident highlights ongoing public fascination with celebrity relationships and the blurred lines between on-screen chemistry and real-life partnerships.
The immediate impact includes renewed media scrutiny of both marriages and discussions about boundaries in celebrity relationships. Brosnahan has historically maintained privacy about her marriage, telling People in 2019 about her frustration with ‘double standard’ questioning that targets her but not Ralph. Representatives for both actors have been contacted for comment but haven’t responded publicly.
Looking ahead, this incident may affect public perception ahead of ‘Superman’s’ upcoming digital release and physical media launch in September. While unlikely to impact professional collaborations, it raises questions about how actors navigate personal boundaries during intensive promotional periods. The situation also illustrates how social media interactions can amplify speculation, particularly when involving high-profile franchise stars.
Ultimately, this episode reflects the challenges public figures face in managing personal lives under constant scrutiny. With no official statements from involved parties, the rumors remain unconfirmed, leaving fans to interpret social media breadcrumbs while the actors focus on their respective careers and families.
