He had been sharing a screen recording of his family playing the game Heads Up but when the video ended, a camera roll displayed on the screen, which appears to show a photo of a penis.
Another photo showed a picture of the star's face with the text, "guard that p****y".
Evans quickly deleted the story but not before screenshots started doing the rounds on social media, quickly becoming the number one trending topic on Twitter.
His Avengers co-star Mark Ruffalo tweeted, "@ChrisEvans. Bro, while Trump is in office there is NOTHING you could possibly do to embarrass yourself. See ... silver lining."
