Love Island's Molly Smith showed off her taut abs as she and boyfriend Tom Clare enjoyed a double date with Casey O'Gorman and Gabby Allen. 

The latest series of All Stars came to a dramatic conclusion when Gabby and Casey were crowned the winners in a shock victory over long-time frontrunners Grace Jackson and Luca Bish. 

Molly, 30, won the first series with Tom, 25, last year, and the couple still going strong now. 

Heading out for an evening out this week, the group celebrated Casey and Gabby's win with a party at Sheesh Restaurant in London. 

Molly looked incredible in a one-shouldered crop top which she teamed with a fitted maxi skirt. 

Meanwhile, Gabby opted for a lace-up corset top with a fringed mini skirt and leather ankle boots.  

Sharing a series of photos to Instagram, Tom wrote: 'The double date happened… well kinda, surprised by their Family & Friends too, big love.'

Viewers were left in shock this month 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 and Grace.

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

The couple 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 and Grace 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).'

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?'

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.

Some wrote: 'SOOOOOOO happy gabby n casey won!!! LOVE THEM #LoveIsland #LoveIslandAllStars #AllStars',

'So happy for WINNERS ... #GabbyAndCasey They had our votes. Really want this to be a #LoveIsland Happy Ever After!',

'You know what… I ain’t even mad at Casey and Gabby winning',

'Well done Casey and Gabby. The only couple that didn’t look like they were trying too hard and seemed to have a truly natural connection with each other. All the best. Hope it works out'.
