From steamy lap dances during the infamous Heart Rate Challenge that sparked Ofcom complaints, to toe-curling scenes that left viewers saying they were “sick in their mouth,” the ITV2 dating show has served up some truly unforgettable - and deeply embarrassing - TV gold.
Over the years, Islanders have pulled out all the stops to impress - or mortify - their fellow contestants, with grinding, stripping and even role-play making regular appearances.
But while some fans are living for the drama, others were left hiding behind their pillows - or reaching for the remote.
From outrageous outfits to awkward encounters, here are the moments that had the nation gasping, groaning… and tweeting in horror.
The Love Island heart rate challenge is a firm favourite among fans and sees the Islanders put on a sexy show to get their co-stars hot under the collar.
But it was on Love Island: All Stars where viewers saw the most raunchiest version of the game so far.
Ekin-Su Cülcüloğlu transformed into a cheeky devil and recreated her iconic crawl across the terrace from series eight in 2022.
But it was Curtis Pritchard's Heart Rate challenge that was the most hotly-anticipated, with the All Stars and viewers being sent into a frenzy.
Curtis channelled his inner King Julien from Madagascar after his 2019 Heart Rate challenge performance.
Rocking some blue shiny shorts, which were tightly fitted and left very little to the imagination, Curtis also rocked a huge feathery headdress in a blue hue.
Thrusting in the girls' faces, twerking and moving his body seductively, Curtis then knee slid on the floor leaving his co-stars and viewers at home gobsmaked.
Ekin-Su couldn't keeps her hands of him as she passionately snogged Curtis on the floor - as the villa boys ran off in shock.
Ekin even rubbed her man's face into her cleavage and moved his head up and down her body.
Viewers were left watching through their fingers as the pair appeared to romp wearing barely any clothes and slammed the episode as "porn".
The steamy moment sent social media into meltdown - with fans branding it "too much" for pre-watershed TV.
Fans were not impressed with the couple's actions and called Ofcom.
Fans were left cringing after a very awkward moment when the girls inadvertently told Liberty Poole her romance with Jake Cornish wouldn’t work.
During a typically candid chat on the terrace Priya asked the group if you can come back from not wanting to rip someone’s clothes off as she discussed her relationship with Brett.
The group pretty much unanimously said it wasn’t possible - leaving Liberty looking a tad baffled.
Liberty was devastated when she was shown footage of Jake talking about her.
In scenes that left her reeling, he said: “She's not all that.
"It's not 100 per cent. I haven't got the girl, that I'm like, f**k me, I want to rip her clothes off. I don't want to fake it, do you know what I mean?"
At the time, stunned Lib asked the girls: "What does that mean he doesn't think I'm fit?" as one said: "No, it was just early days."
But Liberty wasn't convinced and later told producers in the Beach Hut: "To hear that coming from your partner, saying I didn’t want to rip her clothes off, I don’t fancy her, or know if the attraction is there, it is brutal."
Jake finally told her he loved her after weeks of waiting - but the news didn’t go down well with the other Islanders who thought he was just saying it to get her off his back.
Chloe Burrows asked Liberty: "Do you not think he's telling you what he wants to hear?"
Liberty replied: "Is that what all you guys think? Do you think I'm being an idiot?"
Despite protests from their fellow Islanders, Liberty and Jake made it to the final - but then Liberty had doubts about their relationship and left the villa.
Viewers were horrified by Charlie Radnedge's performance as a naked butler.
He stunned fans by performing a string of X-rated moves during the heart rate challenge.
He started off doing the worm dance move before awkwardly whipping off his trousers.
Unfortunately, Charlie was unable to get his butler's trousers off in one clean move.
The estate agent stood in front of the girls in a tong and admitted he wanted to keep it "PG".
The moment left viewers with "sick in their mouths" and called for Charlie to be "arrested".
Yewande Biala is forced to look on as Danny and Arabella Chi lock lips as part of the kissing competition.
Arabella goes to town when smooching Danny, while Yewande - who was coupled up with Danny - said: "I think Arabella kind of went for it with Danny."
Yewande later made a vow to up the romance with Danny after she was accused of not showing him enough affection.
After pouncing on him for a kiss, Yewande can be seen sitting on Danny as he talks to Arabella.
Talking about the incident in the Beach Hut, Arabella says: "I think literally sitting on somebody when they're just having a chat with someone was a little bit strange. I was a bit like, hmmm okay."
Joey Essex performed a rap during the Love Island talent show, which garnered mixed reactions.
He was styled in a backwards cap and wrap around sunglasses while he performed a rap he had written on his phone.
The rap was directed at his girlfriend, Jessy May Potts, and included a "secret mission" element that caused some awkwardness.
Rapping to girlfriend Jessy he said: "Jessy when you picked me for that date it was fate. With my crown on my head. But I lost the cape, Yeah. Going back in the garden was very bake but I risked it all for you girl, after the game of heart rate check it.
"I'll tell you the truth on how I really feel I'm on top of the world and our connection is real. You're a little sort, and you stood on some toes, as it goes.
"You're the one for me. You're my cup of tea. And it bringing out the best in me. I'm lucky to have you by my side. Or let it slide. It's me and you now, baby, you're my rid or die, Let's go!"
As the klaxon sounded a third time, the other contestants applauded but Joey told them, "Wait, wait, wait. When I say secret - you say mission. Secret..."
There was an awkward silence and then Joey asked: "Anyone?"
And he then added: "Well that didn't go that well did it?"
Viewers were left in hysterics after spotting Anton Danyluk’s face drop when Anna Vakili picked Sherif over him.
The gym owner thought he was certain to be picked by the statuesque beauty when she mentioned that the boy she was choosing had a really good body.
The cheeky Scotsman had made it clear he thought Anna was hot and had tried to make a play for her several times.
And standing in the line up it appeared as though he thought his luck was in as Anna stood up and started revealing the reasons why she wanted to pick this person.
Anna said: "I would like to couple up with this boy because in such a short amount of time I've come to really care about him.
"I feel like everytime I'm a bit down he seems to put a smile on my face."
However it was when Anna said: "He's got a really sexy body, which is not bad to look at as well" - that Anton broke into a wide smile.
But when Anna picked Sherif, Anton couldn't hide his disappointment and viewers didn't miss it either.
One wrote: I can’t stop laughing to myself @Anton thinking Anna was talking about him #loveisland
While another joked: "Dying that Anton thought that Anna was talking about him and then picked sherif #loveisland
And a third added: "Anton with the little smile, well that was awkward #loveisland"
Love Island viewers were left in hysterics after Molly Marsh crashed Zachariah's workout with new bombshell Charlotte.
Dubbing the move as "stalking", fans watched as Molly made her way over to the gym area to watch.
Noticing the move, other islands were quick to comment on her antics.
Jess Harding in particular voiced her opinion, calling her actions "so obvious".
Overhearing, Molly then called out Jess, telling her to "come join."
As Charlotte walked away, Jess even pushed her to "go back".
Taking to Twitter as the episode aired, fans couldn't help but laugh at the tension, claiming Molly was exhibiting her partner Mitch's behaviour.
One fan wrote: "Molly is on Mitch level crazy now".
"Molly and Mitchell - mr and mrs unhinged", another agreed.
A third added: "I take back what I said about Mitch 10 minutes ago... Molly is your soul mate".
Olivia Hawkins was called out for her double standards after she took a swipe at Kai Fagan - despite recoupling in Casa Amor herself.
She might have walked back into the Love Island villa with a new man on her arms, but Olivia's takedown of Kai saw her come under fire from viewers.
While Kai faced a "very tough decision" when choosing to couple up with Sanam Harrinanan, he said he hoped Olivia had found a connection in the days they spent apart.
But when she walked back in with Maxwell Samuda... Olivia immediately let loose.
Olivia said: "It’s very telling, and I can’t say I’m shocked. Missing me already? Clearly not enough."
Kai replied: "After a couple of days apart I could tell what is genuine and what isn’t… and I think I’ve got a real genuine now."
However, Olivia didn’t miss her chance to jump in and told Kai everything he’d told her were "lies".
Viewers watching at home called out her double standards.
Taking to X - formerly Twitter - one said: "Why is Olivia being like that? She literally recouped too."
Another fan added: "Olivia you walk in with someone else then act shocked he done the same???"
A third penned: "Sorry... has Olivia not got a whole new man on her arm???? I'm confused."
Mitch Taylor has left Whitney Adebayo fuming after making a disastrous joke about her relationship with Lochan Nowacki.
The islanders went head-to-head in the fan favourite talent show challenge in a bid to impress each other.
But unfortunately for Mitch, his "roast" skit falls flat as he ripped into Whitney and Lochan's romance.
His big moment came after Lochan showed off his frisbee throwing skills for his talent, telling his co-stars that he "played frisbee for Great Britain" a decade ago.
Clutching at his piece of paper, Mitch said: "This is my 2023 Love Island roast.
"Whitney and Lochan, you haven't been through a hard time just yet.
"But until you get out this villa, and them DMs start flying, them frisbee skills aren't going to get you anywhere, son."
Unfortunately, no one laughed.
Instead, a furious-looking Whitney muttered that the only noise in the garden is "the crickets".
