Love Island fans flocked to social media to share their disgust at Tasha Ghouri kissing new boy Billy Brown while wearing Andrew Le Page's ring.
Real estate agent Andrew and model Tasha were seemingly a strong couple having been together since the beginning of this year's series.
However, Casa Amor has led to both straying - with Andrew taking a liking to Coco Lodge and even saying "Tasha who?".
In Tuesday evening's episode, fans watched on as it was the turn of Tasha, who is the show's first ever deaf contestant, to "cheat" on her man in the original villa as cheeky chap Billy leant in for a kiss.
While the action was enough to shock some onlookers, other eagle-eyed viewers took to Twitter to condemn her for doing so while wearing Andrew's ring.
He had sent the momento to Casa Amor in the suitcase he packed for the blonde beauty after the girls were surprised with a trip to the new villa.
And one user exclaimed: "SHE HAS HIS RING ON IM SCREAMING," while another blasted: "Not tasha wearing andrews ring while lipsing Billy."
Others weren't so sure on what they seen - or weren't after to believe it. Another user questioned: "Is Tasha wearing Andrew’s ring whilst kissing Billy?"
And a fourth shared a similar message, seemingly finding it amusing: "LOL was Tasha wearing Andrews ring whilst she kissed billy ???"
Tuesday's edition of the show saw action certainly heat up with many of the couples appearing to be at breaking point.
While Dami Hope continues to get to know new girl Summer, his current partner Indiyah Polack is also testing the waters in Casa Amor with Deji.
Elsewhere, Ekin-Su Culculoglu might have decided Davide Sanclimenti is the man for her, but what she doesn't know is that he's already kissed two of the girl bombshells - and it seems he's keen to pair up with one of them.
And in the teaser clip for Wednesday's episode, emotions seem to be running high as Andrew is seen sobbing with his head in his hands.
While there are no details on what has upset him, it seems to be something major and fans are convinced he has discovered Tasha's actions via the dreaded postcard.
