'You're too skinny': Katie Price has left fans concerned after flaunting her svelte frame on Instagram, with many accusing the star of losing too much weight
Katie has been following a strict exercise programme for the last six weeks in her bid to remain as 'positive as possible' through the difficulties she is currently facing.
Reaping the rewards of her hard efforts, the former glamour model has been showcasing the results of her new found love for the gym on Instagram, but her slimmer appearance led to a slew of fans expressing their worries over the star.
Many were quick to comment that Katie is now looking 'too skinny' amid her heartache, after she posted a selfie wearing a grey crop top tied together at the bust to expose her washboard stomach.
They penned: 'You are far too skinny come on Katie you better than this show your natural Beauty.

'Oh dear..thought no more plastic..how wrong were we..boobs way to big..far too skinny ..hair is lovely though..but at the end of the day pricey is pricey and will do whatever she wants !!!
'Please put some weight on, you’re far too skinny!; She's to skinny but love how long her hair is.' (sic)
Others were quick to jump to Katie's defence, however, and defended her against her critics, insisting the star looks 'fantastic'.
Their comments came as a representative for Katie revealed she has thrown herself into the gym to help heal her heartache. They claimed: '[Katie] has been training for six weeks, after everything with her relationship status and her mum.'
While they added that weight loss was 'never the goal', they said: 'She's only lost a few pounds on the scales, but has reduced inches everywhere.'
The source continued: 'She wants to live a happy, positive life and with everything that is going on with her mum, she wants to feel as positive as possible during this difficult time.'
New mindset: The mother-of-five has turned to fitness following her husband Kieran Hayler's cheating and her mother Amy, 64, being diagnosed with a terminal lung illness
Katie's mother Amy has been diagnosed with the lung condition Idiopathic Pulmonary Fibrosis. The Loose Women star revealed her mum's condition back in September and explained Amy 'hasn't got long to live' due to her illness.
Amy, meanwhile, spoke of her condition and revealed a chest infection had highlighted her illness, following five years of her suffering from asthma. Explaining her diagnosis, she said: 'It's like scarring of the lungs and it actually stops you breathing. It's progessive... in the end you won't be able to breath.'
Along with her mum's diagnosis, Katie has had to deal with splitting from her third husband Kieran, whom she shares two children with; son Jett, three, and daughter Bunny, two.
Katie was left devastated on uncovering Kieran's affair with their children's nanny in August - he previously cheated on the star with two of her best friends Jane Pountney and Chrissie Thomas. Despite vowing to leave Kieran initially, Katie chose to give their marriage another go and the pair had renewed their vows in February 2015.

This time round, however, Katie has insisted her relationship with Kieran is over. The duo had set tongues wagging on social media that they are reuniting, but Katie has since vehemently denied the claims in an interview with The Sun's Fabulous magazine.
But while insisting she won't be giving Kieran another chance after his infidelity, Katie admitted that he will remain in her life forever.
She said: 'He’ll always be in my life just like Pete [Andre] will always be in my life – I’ve got kids with them. Do people need to see a removal lorry leaving my house?
'People can say what they like, I know what’s going on. He’s a cheat, and I’m not putting up with it. That’s it.'
Katie's new get-fit attitude comes as she caused a stir with her ab-baring Instagram post, due to the size of her bust which appeared to be noticeably bigger, and prompted rumours she has had her ninth breast procedure.
