Love Island: All Stars 2025 final down 100,000k viewers since last year’s ending – as Gabby and Casey shock with win over frontrunners Grace and Luca

Love Island: All Stars’ second series is down 100,000 viewers since its 2024 debut. 

The reality show came to a dramatic conclusion on Monday night as it saw Gabby Allen and Casey O’Gorman crowned the winners in a shock victory over long-time frontrunners Grace Jackson and Luca Bish. 

And while the final bagged the highest audience of the series, with 1.2 million viewers, it didn’t perform as well as last year’s final. 

An impressive 1.3 million tuned in to watch Molly Smith and Tom Clare win the debut All Stars season in 2024.

According to overnight ratings, the final episode of the 2025 series had an average viewership of 913,000, garnering 7.87% of the audience share for Monday night. 

However, despite a dip in fans tuning in, the second series of Love Island: All Stars was up by an impressive 89 million streams.

The highest ever series of Love Island was 2019’s series 5 (won by Amber Gill and Greg O’Shea), which had a whopping 3.7million tune in. 

Viewers were left in shock on Monday night when Gabby and Casey were announced as the winners of season two. 

The couple bagged the whopping £50,000 prize during Monday night’s final after beating runner ups Luca Bish and Grace Jackson.

Casey finally got his happy ending with blonde bombshell Gabby after appearing on the show three times previously.

Gabby and Casey had flown under the radar in the leadup to the finale, with bookmakers never placing them as favourites to clinch the £50,000 prize. 

Nonetheless, they managed to storm to victory during the live final – pipping longtime frontrunners Luca Bish and Grace Jackson to the post while Ekin-Su Cülcüloğlu and Curtis Pritchard finished in third. 

Some even questioned if the result was rigged, with Gabby, 33, and Casey, 28, having been devoid of public sentiment online – SlotsCalendar’s data revealed that only six percent of tweets about the couple since they paired up had been 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.

William Hill spokesperson Lee Phelps told MailOnline: ‘Gabby and Casey’s Love Island All Stars victory last night may have appeared a shock on paper, but the result ended up being a big loser for us, with the couple accounting for over a third (35 percent) of stakes throughout the series.’

He continued: ‘While the pair started out as an unlikely 10/1 towards the end of January, our punters appeared to have their heads turned in early February and their price dropped to as low as 4/7 at one point – the shortest odds offered at any stage of the series.

‘Gabby and Casey entered last night’s finale as 6/4 second favourites but proved to be the real bombshells of the series, stealing the crown from Luca and Grace (1/2).’

Speaking to MailOnline, FruitySlots.com’s Jamie Rosen added: ‘Casey and Gabby’s victory in Love Island All Stars 2025 has taken the nation by surprise, and it’s safe to say that the bookies also did not see this coming. 

‘As the ultimate underdogs at 4/1, they defied the odds and caused a huge upset to get their hands on the £50,000 cash prize and prove that anything can happen in the world of reality TV.

‘The bookies had all but written them off, with reality TV betting experts making Luca Bish and Grace Jackson the hot favourites to win at odds of 11/10, making them clear favourites heading into the highly-anticipated final. 

‘But what could have led to this outcome? It was clear that Casey and Gabby’s journey, chemistry, and authenticity struck a chord with viewers across the country, making it third time lucky for Casey, as he made his third appearance as a Islander on the show.

‘The bookies will be left facing a big payout to anyone who had the foresight and saw this shock result coming. The odds were stacked against Casey and Gabby for most of the season meaning their supporters will have won thousands at the bookies’ expense.

‘It also highlights just how unpredictable the outcome of Love Island can be, and could impact future betting trends for reality TV shows, where the experts calculating the odds will think twice before writing anyone off as a complete underdog.

‘Casey and Gabby’s win is a reminder that in the Love Island villa, love and authenticity always have a place at the top, no matter what the odds say.’

For weeks, season eight’s Luca, 25, and season 11 star Grace, 26, had been the bookies’ frontrunners to win the show – garnering a strong online fanbase. 

During the final, as Maya interviewed the final two couples, Gabby reflected on making friends with her ex Marcel.

She admitted: ‘I never thought I would be friends with him. I can unblock him on Instagram now, we can be friends.’

And when asked whether he really ‘chases the clout,’ Casey joked: ‘Can we not mention that word ever again please?’

Ekin-Su Culculoglu and Curtis Pritchard finished third place 

Catherine Agbaje and Omar Nyame placed fourth, leaving Elma Pazar and Sammy Root finished in fifth place 

Before Maya revealed the winners, last year’s winners and Casey’s best pal Tom Clare and Molly Smith joined via video call to wish them the best of luck.

Confirming they can’t wait to go on double dates when Casey and Gabby return home, Molly and Tom had nothing but joyful things to say about the new couple. 

The final garnered mixed reaction from fans on X, with some viewers over the moon with the winners while others not some happy with the outcome.
