She recently jetted back to the UK from Dubai after an extended stay in the UAE city for work.

And Gabby Allen looked on fine form on Saturday as she arrived at Capital Tower in London's Waterloo for a rooftop fitness session with Raise LDN.

The fitness fanatic, 28, was joined by fellow Love Island stars Arabella Chi and Amber Gill, as they beamed away while arriving at the event with pal Lorna Florence. 

Gabby flashed a hint of washboard abs as she arrived for the gruelling workout, donning a white crop top beneath a cropped grey zip-up top. 

She added a pair of white leggings and bright blue trainers to her sporty look, while carrying her essentials in a white bag slung over her shoulder.

The reality star appeared in good spirits as she displayed her toned figure in her fitness gear before heading inside.

Meanwhile Arabella, 30, and Amber, 23, appeared excited for the challenge ahead as they giggled and chatted while walking down the street with their model pal.

Arabella dressed her incredible physique in a pair of khaki leggings, paired with a white hoodie and matching padded jacket. 

She added white trainers and socks to her attire, while she slung a quilted white handbag across her body. 

A newly-slimmed down Amber meanwhile looked amazing in a black padded jacket, black leggings and bright pink trainers. 

The beauty busied herself with her phone while strolling with her fellow fitness enthusiasts as they made their way to the fitness event. 

The Love Island winner recently revealed that vile social media trolls motivated her to overhaul her fitness regime after unveiling her incredible one stone weight loss.

Amber who slimmed down with the help of a personal trainer, admitted she decided to get in shape after piling on the pounds by gorging on takeaways in lockdown.

Since unveiling her impressive weight loss, Amber, who since launched the workout platform Amber Flexx, said she's never felt better, and urged her fans to take on the same challenge before lockdown restrictions are lifted.

Amber told The Sun that like most of the nation her weight crept up during lockdown, after her previously fast-paced life helped to keep her slim.

She said: 'The only enjoyment came from planning what I was going to eat. If I wasn't in the gym I couldn't motivate myself and eating healthily went out of the window.'

'I stopped getting enjoyment out of taking selfies or sharing photos on Instagram. I ordered takeaways because I didn't like cooking, and was snacking because there was nothing else to do.' 

Amber added that she decided to do something back in October when vile trolls started commenting she was 'fat' under a TikTok post.

She added: 'After some horrible comments, I was thinking, ''I'm just going to start exercising and see what happens''.'
