Sam's super skinny post break-up body

She may have just broken up with her boyfriend Sasha Mielczarek days ago, but fans are concerned that Sam Frost's svelte figure showed the signs of their relationship breakdown way before it happened.

The 27-year-old 2DayFM radio host, who found love with construction worker Sasha on The Bachelorette in 2015, recently released a statement claiming their 18-month romance has come to an end.

However fans were worried about Sam weeks ago when she shared a bikini snap on Instagram showing off her slender frame.

The former Bachelorette shared a full body snap of herself in a bikini at the beach with a massive grin on her face.

But while she looked stunning in the picture, fans were quick to comment on her lithe frame.

One follower wrote: "'Why did you lose so much weight?

Another added: "Please people we all don't need to look like this to be beautiful."

"Too skinny," wrote one person of the beachside snap.

But the much-loved radio star's supporters quickly shut down the "body shamers".

"You're beautiful inside and out," one follower wrote, with another adding, "Body goals."

Others added that us gals should be supporting each other regardless of our size.

Just days later, fans were again left concerned for the star's health after she appeared in a video on Instagram looking overly bronzed while showing off her bony chest.

Clearly aware of her very dark complexion, Sam addressed the camera, joking, "Hi guys it's me Sam, spoilers I look quite dark today. I'm not sure if you can tell in this light but orange is in? Maybe?"

Sam also made light of her tanning fail on her own personal Instagram story, sharing a selfie and writing, "Little bit too tanned today."

Sam's personal trainer, Blake Worral-Thompson also recently shared the secrets to the star's fitness regime, saying her weight loss came down to training five days a week.

"We focused on high-impact and high-attack weight training in order to burn fat," Blake told OK! Magazine.

And her hard work in the gym seems to be working a treat as the radio personality has previoulsy admitted to losing 12kg after appearing on the 2014 version of The Bachelor where she famously won the heart of Blake Garvey, only to be dumped weeks after for runner-up Louise Pillidge.

"I was really, really proud of myself… I worked so hard and it’s not easy," Sam told OK! Magazine about losing the weight.

"In the house, we did absolutely nothing and we just sat around eating the whole time.

"I was eating chocolate every single day, and just heaps of bread."

Indeed Sam shed the pounds and since then her frame has been drawing a lot of attention on her social media pages.

So much so that the constant scrutiny of her figure and her personal life caused her to shut down her Twitter and Instagram account earlier this year.

"To the fake accounts heavily trolling me online & into my personal life. If you wanted to break me. Congratulations you have won. #broken," she wrote online.

However it appears that it took a toll on Sam and Sasha's relationship and the pair announced earlier this week that they had parted ways.

“After 18 months together, Sam Frost and Sasha Mielczarek have come to a mutual decision to end their relationship," their manager told Be in a statement.

"It is important to stress that there is no bitterness or scandal, they have just come to the realisation that the best way forward is to separate. They wholeheartedly respect and cherish the friendship they have for one another which will continue moving forward.

“They wish to thank everyone for their love and support over the past 18 months," she added.
