Love Island: All Stars winners Gabby Allen and Casey O’Gorman threw their arms up in triumph as they led the finalist arrivals at London’s Heathrow airport on Wednesday night.

The couple emerged the surprise victors during Monday’s grand final, having beat show frontrunners Grace and Luca Bish to the top sport – who both cut glum figures as they strolled through the terminal. 

Gabby and Casey could barely keep the smiles off their faces or their hands off each other as they received a heroes welcome after touching down on home soil following their win in South Africa.

They were joined by fellow finalists Ekin-Su Cülcüloğlu and Curtis Pritchard, Elma Pazar and Sammy Root and Catherine Agbaje and Omar Nyame, who all put on loved-up displays at the airport. 

Dressed in a blue tracksuit, Casey, 28, showed off a glimpse of his chiseled abs as he launched his hands in the air in celebration, following his third stint in the villa.

Meanwhile, Gabby wrapped up in a fluffy cream coat which she wore over a white sweater and pale grey joggers.

The loved-up pair posed for several snaps with their fellow finalists before continuing to push their luggage through the concourse.  

Meanwhile, Grace, 26, dressed down in an all-black ensemble and sported a pair of headphones around her neck as she walked hand-in-hand with partner Luca, who opted for a crisp white T-shirt and grey joggers.

The pair appeared serious and failed to raise a smile when they first arrived, however, they soon cheerfully joined in with the festivities.

Grace was seen posing with champion Gabby and pal Catherine as they larked about at the airport following their long flight. 

Ekin, 30, and Curtis, 29, who finished third, appeared smitten as they strolled together, with the dancer wrapping his arm around his girl before planting a tender kiss on her head. 

Actress Ekin looked overwhelmed with the attention as she posed in an ab-flashing black crop top and dark mauve joggers. 

The couple were greeted by Curtis’ former Strictly star brother AJ Pritchard, 30, who brought along huge gold balloons spelling out their initials. 

Elsewhere, fourth place finalists Catherine, 24, and Omar, 26, both dressed down in dark, comfy tracksuits as they posed for sweet snaps together.

Elma, 32, and Sammy, 23, who ended up in fifth place, only had eyes for each other as they enjoyed a pᴀssionate kiss at the airport. 

Dressed in a white tracksuit, TOWIE star Elma couldn’t get enough of her shorts-clad beau as she leaned in for a romantic smooch.  

It comes as Casey and Gabby won the series by less than three percent, it has been revealed. 

The couple managed to storm to victory during the live final on Monday – pipping long-time front-runners Luca and Grace  to the post while Ekin-Su and Curtis finished in third. 

But despite emerging victorious, the break down of voting has shown it was a very тιԍнт race.

On its official Instagram account, Love Island shared a graph of how the votes were split between the finalists, with Casey and Gabby securing the win with just 33.37 per cent of the vote. 

It was less than three percent more than runners up Grace and Luca who finished on 30.38%, while third placed Ekin-Su and Curtis secured 21.74 per cent of the vote.

The results come after some people questioned if the end result was rigged, with Gabby and Casey having been devoid of public sentiment online – as fans cited Grace and Luca’s last minute drama surrounding texts alleging she had said she’d do anything to win.

Completing the final vote tally, Catherine Agbaje and Omar Nyame received 8.14% of the vote, while Elma Pazar and Sammy Root finished on 6.36%. 

SlotsCalendar’s data revealed that love for Casey and Gabby online ahead of the final was scarce, with only six percent of tweets about them since they paired up positive. 

While social media users were baffled at the result, it has resulted in bookmakers paying out thousands, because of a third of the stakes were placed on the underdogs.
