Dalia Malek shared an image of the man's Tinder profile snap on Twitter after noticing something rude in the background.
If you're going to share a mirror selfie on social media or dating apps, it's always worth checking what's going on in the background.
A man chose a photo of himself posing in the gym changing rooms for his Tinder pic - but apparently failed to notice a naked mystery man behind him.
Stand-up comedian Dalia Malek, from San Francisco, was surprised by the unusual background detail when she matched with him.
She shared the image of the man's gym selfie on Twitter , joking that he's her "soulmate".
