She's been battling for the past four months to slim down after declaring she wasn't happy with her 17-stone figure.
And now, after sticking to a diet regime and attending bootcamp sessions, it seems all Gemma Collins' hard work has paid off.
The 30-year-old reality TV star was spotted showing off her newly-slim figure in a black monokini while on holiday in Marbella.

Gemma revealed earlier this month that she has so far managed to shed an astonishing 3st 9lb, taking her down three dress sizes.
Talking about her new body, Gemma said: 'I can’t wait to get down to Ann Summers! I've never felt sexier.
'As much as I said I was confident before, I really feel sexy now, not fake sexy. It was false confidence before.'

But she admitted that the new way of life had been anything but easy - particularly putting herself through the gruelling classes at the No.1 Boot Camp in Norfolk.
She said: 'I was packing my bag after three days. It was so different to what I was used to and it was such a shocker being in such a disciplined regime.
'I sent my friend down to the trainer to tell him I was leaving because I didn’t have the guts to say it myself.'

Earlier this year, the 5ft 9in reality star spoke about how she piled on the pounds over the last five years following a heartbreaking miscarriage and subsequent break-up from her long-term boyfriend.
Before beginning her weight loss journey, Gemma wore size 20 (US size 16) and weighed 17 and a half stone. And while she looks incredible, she is keen to lose six stone in total - taking her to a size 12 (US size 8).
Explaining why she wanted to lose weight, Gemma said: 'I can’t say I only ate salad because, clearly, I do overindulge.

Larking around: The 30-year-old Only Way Is Essex star seemed in good spirits as she enjoyed her mini break
'But I’m not a sumo wrestler, I’m a human being. I want the old Gemma back. I say I am still proud of my curves, but I want to be healthy. I know I'm obese and it's not doing me any good.
'I'm never going to be tiny, I would look ill, but I need to lose a few stone.'
