Gabby Allen looked incredible in a daring black minidress as she attended NYX cosmetic's Buttermelt Gala at The Old Sessions House in London on Wednesday.

The Love Island All Stars winner showed off her jaw-dropping figure as she went braless under the strapless number. 

Gabby put on a leggy display in a pair of towering heels and accessorised with a dazzling gold pair of drop earrings. 

Styling her long blonde tresses in voluminous curls, the reality star flashed her gorgeous smile as she posed for the cameras.

Joining Gabby at the bash was Demi Jones who turned heads in a stylish one shoulder beige midi dress which boasted a feathered side split.

She opted for two long matching gloves and added inches to her frame in a pair of towering heels. 

Guests were treated to a performance by DJ Yuki as they celebrated the launch of the brands new buttermelt glaze skin tint and buttermelt highlighter. 

The party comes after Gabby returned from a lavish Dubai getaway earlier this month. 

She displayed her gym-honed physique in a very skimpy bikini as she modelled her outfit of the day in an Instagram post.

The TV personality looked out of this world in the tiny two-piece as she flaunted her jaw-dropping abs.

Gabby looked happier than ever on her lavish trip away in Dubai as she continued to soak up the sun. 

Making a brief appearance at the end of the video, Casey O'Gorman walked in on her shot to give her a kiss. 

Gabby recently clarified her relationship status on her Instagram stories after speculation about her jetting off alone.

She quipped: 'Side note: Yes believe it or not, a girl can go on holiday with her family without it meaning her and her fella have ended... he's flying out on Sunday to see me.'

Gabby and new partner Casey, 28, won Love Island All Stars earlier this year.

The couple bagged the whopping £50,000 prize in a dramatic conclusion over long-time frontrunners Grace Jackson and Luca Bish.

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 lead up 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 and Casey 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.'

He continued: 'The couple accounted for over a third (35 percent) of stakes throughout the series.

'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.
