In her brief 48 hours on the show, the model and influencer coupled up with Aaron, dodged a kiss from Toby, made pals with all the girls – and picked up a lot of new fans.
Her Love Island journey may be over – but a lot of viewers are hoping she will be sent back in.
Either way, the ‘it girl’ of the season is surely moving on to bigger and better things. Here are seven facts about the Glenrothes girl you may not know.
This is what Shannon really thought about the other islanders
After her shock dumping, Shannon appeared on Love Island Aftersun to discuss her brief time on the show.
When asked by host Laura Whitmore what she thought of everyone in the villa, she said: “Should I spill the tea? I mean Libby is the best human ever, Kaz is just energy.
"I think some people are playing up to the cameras, I think Chloe’s playing tactics. But it’s a game show it’s to be expected.”
Shannon has condemned the abuse Chloe Burrows has received since appearing on the show.
There was a backlash after the 25-year-old chose to couple up with Shannon’s partner Aaron Francis – with Chloe’s family saying she received hundreds of death threats.
Speaking on Good Morning Britain, Shannon said: “It's a game show, you know she’s got a job to do. The fact she is receiving such horrible feedback from everyone, it's not really nice.
"Everyone needs to practice what they preach which is to be kind."
Shannon Singh was the bookies’ favourite to win Love Island
Before she even went into the villa, Shannon Singh was the female contestant with the highest odds to win Love Island.
On Monday (June 28) she had 3/1 odds with Bet 365 and a 25 per cent probability of winning.
The top male islander was Brad McClelland, with even higher odds of 2/1.
But Brad’s nan was against the pair coupling up. According to the Mirror, his gran, who he lives with, is “terrified” Brad will end up with Shannon. The fear stems from comments Shannon made about having sex eight times a day.
"I hope he doesn’t end up with her or that back bedroom will be ruined,” the 75-year-old said, “I’d need the telly on full blast all day.”
Shannon Singh is a former glamour model
Shannon, from Glenrothes, got her first glamour modelling contract when she was 18 – and both her parents were supportive of the career move.
"My mum was like ‘you should do glamour, you should do page three’,” Shannon told BBC podcast Brown Girls Do It To, “She took the topless photos of me and we sent them off to a London agency and I got signed within 11 minutes.
"It never bothered me, I think I’ve always been really confident with my body. Boobs are just boobs, I really don’t get the big hoo-ha with them.
"I’m probably getting judged so much. My mum and dad have never made it an issue.”
Shannon also revealed she received online abuse for her topless photos, but she has no regrets.
She said: “I loved those days, I’ve got nothing to be ashamed of, they were my glory days.”
Now Shannon Singh models for Rihanna’s Savage X Fenty
Shannon has modelled for Nastygal, Savage X Fenty, and Pretty Little Thing.
She is signed up to the HL model agency which says she’s 5ft 4ins and a UK size 6.
The 22-year-old said she had made ‘good money’ from OnlyFans – a website where people pay to see pictures.
But she recently deleted her account after Reddit users started leaking her photographs without her consent.
Besides modelling, Shannon can also DJ – so we might not need Craig David back on the decks this year.
She has her own YouTube channel with 10,000 subscribers, where she shares vlogs makeup tutorials, and clothing hauls.
But it’s Shannon’s Instagram which she uses most as an influencer, sharing her posts with her 300,000+ followers.
The model had an estimated net worth of about £150k – before she’d even set one foot in the Love Island villa.
Shannon’s dad used to be a stripper
Shannon must have got some of her body confidence from her da’.
She told podcast Brown Girls Do It Too that her father, who is of Indian descent and previously from Birmingham, used to be a stripper.
“I think it’s absolutely jokes, I love it,” she said, admitting that at first she and her brother did not realise why they would drive around in a Honda with ‘sweet cheeks’ scrawled on it in pink writing.
She said: “When we got to high school, people would be like ‘your dad done my mum’s hen do’.
"[My brother and I] had a bit of a mortifying stage. Now I think it’s jokes. Indian guy stripper, you just don’t expect it.”
Shannon, who is proud of her dad and of her unorthodox upbringing, told The Mirror: “When people hear the name Singh, people automatically assume that I’m from a traditional Indian household, but it’s like polar opposites.
"Bless my dad – it was a long, long time ago he was a stripper, but it shows you I haven’t been brought up in a traditional household and I’m proud to say I haven’t.
She’s a gamer on Twitch
It turns out Shannon is partial to a bit of Call of Duty (COD) and uses the video streaming platform Twitch.
"I game, I Twitch, I play COD,” she told Aaron in the first Love Island episode, “No I actually play it like really good.”
Shannon’s Twitch account username is @ShannonSinghhh and she has 1.9k followers.
Her account is mainly focused on gaming, but Shannon also shares ‘get ready with me’ style videos and says she’s open to a bit of Mukbang – which is when people eat and chat on camera.
Shannon loves dogs
Shannon has her own little pack of four-legged friends.
Sharing a picture of her pugs Pepper and Peaches on Instagram, she called them “the best lock down company you could ask for”.
And in a video on her YouTube channel, she goes on a walk with her Northern Inuit called Troy.
“He’s quite old now,” she says, “So I take him on a nice big walk, and then I take the other little ones around the block because they’re so small, they only need a little walk.”
Shannon Singh’s ‘type on paper’ is…
Shannon admitted none of the men in the villa were for her. But what is her type then?
When asked what she’s looking for in a romantic partner, Shannon said: "I don’t feed off looks, I feed off energy. I need someone with personality. Just someone I can have fun with.
"Obviously, they’ve got to be handsome, but if he’s a handsome hunk but it’s like talking to a brick wall and I’d rather watch paint dry, it’s not going to be great.”
In the villa, she says she wouldn’t be with someone just because they’re “convenient”, and told The Sun she wouldn’t crack on with someone if another girl has her eye on him.
She said: “If I've got some of the girls telling me how much they like a guy I'm not going to be that awful person who cracks on.
"I'm not going to s*** on someone for the benefit of me."
Love Island is on at 9pm tonight on ITV2 and ITV Hub
