American actress Rachel Brosnahan, who recently played Superman's love interest Lois Lane, is currently trending after a clip from the set of her recent movie, Superman, circulated online. In it, she was allegedly seen kissing her co-star David Corenswet (who played the titular role), despite the director James Gunn calling “cut” from behind the camera.However, social media users are now concerned with Brosnahan’s husband, Jason Ralph, liking a comment under his June 2 Instagram post, shading his wife and Corenswet, and accusing them of seemingly having an affair, off-screen. Ralph is also an actor and theater producer.“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. Like bro... let’s have some self-love and stand up for yourself, man, leave her to be with him if she wants that much at the end of the day,” the comment by @duelewar read.Jason Ralph has since turned off his comments for the particular post that showed a smashed banana and its peel lying on the ground, with a portion of his brown shoes visible. However, an X user @corensfilm shared a screenshot of Ralph liking the comment with the caption:“Rachel Brosnahan’s husband… you’re gonna be dealt with. Watch your back.”It has since circulated across platforms and amassed diverse reactions from fans of the actress and Corenswet. While some considered Ralph's comment passive-aggressive, others thought he was sarcastic and mocked the commentator.W @live4gaLINKone thing about men is that they will always be insecure bc rachel has been nothing but gracious for entire superman promo cycleStart The Apocalypse DEADA**! @DollRuinedLINKthat's more embarrassing than anything she could do omgAJ @777AngelNumbersLINKembarrassing yourself and your hot wife publicly bc you’re insecure is a…choiceArt is a way of survival @yourfavnookLINKLiking comments like that publicly is weird...Others continued by defending Ralph.Kahnjutsu @TheCaramelKahnLINKYou can’t decipher someone’s intention over liking a silly postDyl @floridakiloz673LINKYou know they're on the couch giggling while they read that comment tooTYRANT @ioutsoulduLINKI feel like he just found the comment funny…Neither Rachel Brosnahan nor Jason Ralph has responded to the fan reactions.
