The heart rate challenge sent shockwaves through the villa on Monday night's dramatic episode.
It was Helena who was at the centre of the most shocking scene after whispering something wild in ex flame Harry's ear during her dance.
As she danced around him in her skimpy underwear she whispered in his ear 'I want to f**k you' in a shocking moment.
It came just a few hours after she said to Harrison that he was the only one she was interested in in the villa - causing her to clash with his current partner Toni.
And viewers at home gobsmacked by the X-rated comment as they penned on X: 'What did Helena say to Harry?!?! #LoveIsland #LoveIslandUK.',
'I CANT WAIT TO WHAT? THAT MAN DON'T LIKE YOU HELENA. #LoveIsland #LoveIslandUK.',

She read: 'Islanders, it's time to get each others' pulses racing in tonight's Boys vs Girls challenge. #HeartthrobMode #BootyandBeats'.
The girls went first, with Toni leading the way, and attempted to raise the boys' heart rates with saucy performances.
Alima's heart-racing entrance stunned the men while Emily dressed like an angel and Shakira throwing rose petals.
He later asks Tommy to pass the cheeky message on and Dejon looks shocked when he hears what Helena said.
The boys then took their turn to raise pulses too - Tommy's go-to was a whopping bouquet of red roses, while Conor tried his best with a Rugby ball.
Harrison donned pleather as he tries to impress the girls while Giorgio dressed like a waiter and poured chocolate on his torso.
As for Harry, he wore gold angel wings and chooses to whisper back in Helena's ear.
Dejon's trick involved him lying Meg down on the floor.
At the end of the challenge, the Islanders are told who raised their heart rates the highest and the results caused shock waves amongst the group.
Shakira was left fuming that her partner Harry's heart rate was raised the most by ex flame Helena.
The evening before, Shakira confronted Harry about his kiss with Helena during the game of Snog, Marry, Pie.
She asked him: 'Why did you do it?'
Harry replied: 'Because I had no reason to kiss anyone else.'
It came just a few hours after she said to Harrison that he was the only one she was interested in in the villa - causing her to clash with his current partner Toni
It came after she said she liked Harrison (seen) the most
'You could've kissed anybody, then to get down on one knee like, I was going to be buzzing after I watched you snog her…'
Harry attempted to make amends and said: 'I don't want to hurt you, I haven't tried to hurt you Shakira.'
She replied: 'But you have. Everything in me is telling me to burn it.'
Later on in the evening, the Islanders were called to recouple and the boys were given the power to choose first.
Love Island continues tonight at 9pm on ITV2 and ITVX.
