Evans, 39, shared a screen recording of himself playing Heads Up with his family, but at the end of the clip people caught a quick glimpse of a camera roll - with one picture being of a man's genitals, along with another of Evans' face accompanied by text that said 'Guard that p***y'.
The post was deleted shortly after, but many fans had been able to screenshot it before it disappeared and began posting the images online.
While the actor is yet to address what happened directly, he's now posted on Twitter with a pretty ingenious quip, having taken the opportunity to urge Americans to vote in November.
He tweeted: "Now that I have your attention.... VOTE Nov 3rd!!!"
Evans also added a face palm emoji and a shrugging emoji in reference to his blunder.
His Marvel co-star Mark Ruffalo addressed the elephant in the room the other day, pointing out in a Twitter post that there was at least a 'silver lining'.
Tagging his pal, Ruffalo wrote: "Bro, while Trump is in office there is NOTHING you could possibly do to embarrass yourself. See... silver lining."
Many other social media users also came to Evans' defence as others shared screenshots of the image, calling on people to respect the actor's privacy.
One tweeted: "Everyone has seen a penis before. There's no need to see this particular person's penis. Leave Chris Evans alone."
Another wrote: "Before sharing Chris Evans nude, remember that the actor suffered an anxiety disorder with the rise of his Hollywood career and even refused to be Captain America on several occasions for fear that fame would affect him and his family."
Some even shared alternative photos of the star to help fill feeds with more 'wholesome' images, promoting a feeling of positivity and support while ensuring he was trending on Twitter for all the right reasons.
Somehow, I feel like Evans has got the last laugh with this one.Featured Image Credit: PA
