The drama-filled challenge saw Harriet Blackmore and Ronnie Vint raise each others' hearts the most, while couple Elma Pazar and Sammy Root were least.
But Gabby admitted she was left feeling 'mugged off' after the raunchy challenge saw her beau Casey O'Gorman's heart raised most by fellow Islander Grace Jackson.
After the results were read out, Gabby looked furious before she whispered under her breath the shock confession that her and Casey had slept together.
'Also 'cause I f***ing slept with him as well, so embarrassing,' Gabby said - after the pair went to the hideaway together earlier in the series.
Debriefing later in the evening, Gabby told Casey: 'I just wanted your heart rate to go up for me.

'Yeah so did I,' said Casey, before Gabby added: 'Yeah I know but you... you did not do what Curtis did. Curtis shocked me.'
Casey said: 'Yeah but my heart rate was raised by you as well, I loved yours.'
'Sure,' Gabby said as she looked away. 'Oh my god. I did, I loved it,' Casey replied.
Gabby added: 'I'm allowed to just be a little bit miffed by it,' before Casey said: 'Okay be p***ed off then.'
'I'm not p***ed off anymore,' Gabby said. 'But we're having a conversation about it.'
'You sound pretty p***ed off,' Casey said, to which Gabby replied: 'It just didn't feel nice that's all. Like I know there's nothing in it. I really do know there's nothing in it. It just doesn't feel nice.'
Stunned viewers were quick to catch Gabby's confession as they wrote on X, formerly Twitter: 'Did gabby just say she slept with that boy on national television,';
'Omg they are really letting the tea slip this year?? Not even using code words, Gabby told us in bold,';

Elsewhere in the episode viewers were left all saying the same thing as Curtis Pritchard raised six of the girl's heart rates, the most out of all the boys, with his X-rated routine.
The dancer, 28, once again donned his iconic feathered hat, which made him a internet sensation during his first villa stint, and danced energetically in nothing but a pair of hot pants.
He then grabbed Ekin-Su Cülcüloğlu, 30, who he is coupled up with, and lifted her off the ground as they writhed and simulated sex while their fellow singletons screamed.

When it was later revealed that Curtis had raised the most heart rates, viewers at home were convinced the majority of the girls were actually terrified rather than tantalised.
Taking to X they said: ' Heart was racing for Curtis cuz [sic] they were scared': 'I’m CRYING i’ve never seen Catherine move so hastily her and Tina were SCARED of creepy Curtis. this scared me more than his Hollyoaks acting':
'The only reason the boys won is because Curtis scared the s*** out of [the girls]: Curtis raised their heart rates because they were terrified!': 'Their heart rates were all raised the most by Curtis because they were all TERRIFIED of him him'.
Harriett Blackmore, 24, later proved the fans theory right when she giggled that he pulse raised out of fear.
