IT'S the sexy challenge that often ends in tears - and last night's was no exception.
Love Island viewers lapped it up as the All Stars stripped into revealing lingerie and raunchy outfits for the heart rate challenge - and were shocked by the results.
The villa's most solid couple, Molly and Tom, raised each other's heart rates the least, while Callum was left hot under the collar as his pulse soared for his ex.
Molly also raised the heart rate of Anton most out of all the girls - with his girlfriend Georgia Harrison choosing to throw petals over the lads rather than perform a sexy dance.
As usual the erotic outfits on display didn't disappoint, and Georgia Steel even whipped out a pair of handcuffs.

But how does last night's challenge compare to these legendary performances from series gone by?
Amber Gill - 2019
We all love Amber now for her hilarious Love Island takes on Twitter, but during her season the beauty was too sexy for her own good.
She had the last laugh after her sexy lap dance set ex Michael Griffith's pulse racing more than his new girl Joanna Chimonides.
Joanna awkwardly raised her hand to her face, while Jordan Hames did his best to reassure Michael, telling him: "It's happened to the best of us, bro."
Megan Barton Hanson - 2018
Dressed in a revealing Moulin Rouge outfit, Megan set plenty of pulses racing – and it wasn't just the boys.
Former contestant Olivia Atwood admitted feeling turned on herself while watching at home.
Taking to Twitter, she wrote: “Right not having them results. Megan even turned me on a bit then.”
The glamour model got so swept up in her sexy dance she later said, “I don’t know what come over me!”
Maura Higgins - 2019
There's no debate Maura Higgins is a bonafide hottie, but she took things up another level as a sexy cat woman during her season.
Love Island's Luca Bish cosied up to stunning blonde at New Year's Eve party
The Irish beauty marched out in a leather outfit complete with a fishnet bodysuit and cutout leather pieces, leaving very little to the imagination.
And of course, matching kitten ears in her hair.
Seeing her opportunity, Maura cranked up the heat, storming over to Curtis Pritchard who couldn't resist her moves and the pair shared their first kiss.
Tasha Gouri - 2022
During her raunchy performance Tasha transformed into Barbie and posed inside a human size Barbie box.
The dancer then showed off her best moves, whipping her blonde hair around the boys' faces.
But the most jaw-dropping moment came when she shared a racy snog with her villa pal Paige Thorne.
Ekin-Su Cülcüloğlu – 2022
She may have worn white, but there was nothing virginal about Ekin Su's seductive heart rate challenge routine.
Dressed as a sexy bride, she set out to prove to Davide she was wife material - and concluded her dance with a passionate snog.
Jordan Hames - 2019
Sexy Jordan – who since Love Island has had a chic fashionista makeover – oiled himself up, donned a bow tie and collar to play a naughty butler.
He can serve us drinks any time.
Gemma Owen - 2022
Gemma didn't leave much to the imagination with her sexy riding-themed outfit for the challenge, which was cheeky to say the least.
She made a beeline for her villa flame Luca Bish, but it all kicked off when it was revealed Gemma's heart rate increased the most for her ex Jacques O'Neill, with Luca promptly throwing a strop.
And then there were these routines, which were memorable for, eh hem, different reasons...
Mike Boateng - 2020
The former police officer gave us one of the most hilarious heart race challenges when he pulled out all the stops to impress the girls.
Sporting black hot pants pulled right up his bum with a tuxedo bow and matching cuffs, Mike got up to all kinds of antics during his dance.
He licked their legs and grinded on the girls, leaving everyone in hysterics.
"I had pure bum crack in my eye," shrieked one after Mike's magic show.
Curtis Pritchard - 2019
Curtis became a viral internet meme when he emerged in a feather headdress and pink hot pants.
Some fans compared him to King Julian from the animated film Madagascar as he gave us one of the most unforgettable heart race challenge dances ever.
Mary Bedford - 2021
Strolling out in an ill-fitting Little Mermaid costume, Mary certainly did her best with a bizarre costume choice given to her by producers.
While the rest of the girls slipped into raunchy get-ups, Mary was left with a baffling outfit that left her looking like Ariel.
The frizzy red wig and skirt of green scales raised eyebrows online.
But Mary has had the last laugh - transforming into a stunning mermaid for Halloween just months later.
Jake Cornish - 2021
The water engineer left then-girlfriend Liberty and viewers gobsmacked with his very sexy dance routine.
Jake stormed out in a cape, oversized fake beard and a horned helmet – serving the Islanders sexy viking vibes.
Even though the girls and viewers at home were left scratching their heads about what his costume was, Jake was inspired by his own performance.
He later admitted: “If the Dreamboys [strip dancing troupe] are watching, get on my phone now. Get me there today, that’s what I thrive off!"
Mal Nicol - 2023
During her series Scottish bombshell Mal Nicol dressed up as a sexy cheetah - but rather than embrace her inner sex kitten, she appeared to find the whole thing hilarious.
She arrived at the fire pit in fits of laughter and fans remarked on how "awkward" she appeared.
One viewer remarked: "Mal’s full performance. Most of us would be this awks, let’s be real," a fifth chiemd in.
Another said: "I can’t even lie Mal would be me asf trying to do that challenge."
