An influencer has revealed the moment she found out her boyfriend was cheating on her thanks to the Live photo iPhone feature.
Serena Kerrigan, who starred in the latest season of MTV reality series Siesta Key, took to TikTok to share the tale as well as the incriminating snap, in a clip that has since gone viral.
"When the guy you're dating says he misses you, but then you click the live photo," the 27-year-old from New Yorker wrote on the video that's now had 7.4M views.
"Looks like you have some company," she added in the caption.
The photo looked to be showing off a neatly made bed, before accidentally also revealing his female company, which the live photo feature captured as she plonked herself onto said neatly made bed.
The Live Photos function means your iPhone records what happens 1.5 seconds before and after you take a picture, as Apple explains on its website.
That way you not only get a photo, but you capture a moment with "movement and sound".
Though in this case the moment was likely not one the man wanted shared and yet now it's had more than 1.4M likes on TikTok.
"My jaw dropped faster than she did," one person commented.
"Apple said, 'I got you sis'," one wrote, while another agreed: "Steve Jobs is the real MVP."
"Omg I could just feel the heart drop," was another comment.
And it's not the first time a handy tech feature has helped bust an unfaithful other half.
Recently, another woman revealed how a SnapChat filter ended up helping her bust her cheating boyfriend.
The automated 'Magic 8 Ball' filter answered her question about whether her boyfriend was cheating on her with "You better believe it".
And while her partner appeared shocked at the time, assuring her that he "wasn't cheating", the woman Sophie revealed that he WAS actually cheating on her.
