She embarked on a fitness journey after her weight crept up to 12 stone and 13 pounds after 'hitting rock bottom' in lockdown last year.
And Frankie Essex showcased her incredible figure following her weight loss as she took to Instagram on Thursday.
The former TOWIE star, 33, who is in Mexico with her cousin Chloe Sims on a 'work trip', put on a busty display in a plunging swimsuit.

Frankie flaunted her ample cleavage in the revealing number which plunged down the naval.
She teamed the look with white light-weight shorts and blue tinted sunglasses.
Frankie addressed why she flew to Mexico in a previous post, amid the recent backlash from reality stars who have jetted abroad while the nation is in lockdown.
Working up a sweat: The television personality also shared a snap of herself at the gym of her hotel and captioned it: 'Still on it mate!'

She captioned the upload: 'PROGRESS! Officially 4 weeks into my @mfgoalgettersuk plan now & i’m feeling good. My clothes are already feeling looser & my body so much lighter.
'Yes I’ve still got a long way to go but I’m proud of how far I’ve come already...especially after overindulging over the Christmas & New Year - It’s definitely going to be harder now with another Lockdown & staying indoors but I’m determined not to let it get the best of me like last time...'

In a separate Instagram Story, Frankie videoed her progress and confessed to being 'really happy' with her current results.
It comes after Frankie revealed that she gained weight after 'hitting rock bottom' in 2020.
In an exclusive interview with MailOnline, the former TOWIE star admitted she 'felt like s***' when she discovered her weight in November after 'swerving those scales' during the coronavirus pandemic.
The beautician said she aimed to lose up to one and a half stone in eight weeks, and she would also embark on an exercise regime set up by her personal trainer beau, Luke.
'I make so many excuses', the media personality told us. 'I got on the scales about two weeks ago at the night time - which you shouldn't really do - and I was 12st 13lbs. I just thought, ''Oh my God!''
'I kept making excuses until I hit rock bottom and got on the scales. I didn't even tell Luke at first, but I'm only hurting myself at the end of the day. It's not really about the dress size for me, as if I lose weight, I'd still be able to fit into a lot of my clothes.'
Candid: The beautician shared images of herself in underwear in December in a bid to document her progress
