Katie Price baffled her fans by sharing a snap of twin babies on her Instagram Stories on Tuesday - as she prepares to star in a Channel 4 documentary about her IVF struggles.

The former glamour model, 46, captured two twin newborns, one wearing a pink romper and the other one wearing a grey one.

She was seen posing her hand gentle placed on the tots, although their faces were not visible.

It is unsure whose kids they are, but are not her sister Sophie's - who revealed in July she was pregnant with just one girl.

Her update comes after Katie sparked concern among fans earlier in the day, as she looked noticeably thinner while modelling a stylish cardigan for an Instagram clip.

But the TV personality exclusively told MailOnline that her drastic weight-loss is the result of a new gym regime, after sparking concern from fans.

The internet star left fans rushing to the comments after modelling a burgundy jumper dress - as she once again promoted her friend's clothing brand JYY London.

Fans wrote: 'Sorry, but you look unwell': 'What happened to her legs': 'What's she done?': 'Oh Katie this breaks my heart. Where are the people [that are] meant to be looking out for her': 'Her legs have gone skinny': 'What's happened to her legs'.

Following the concern a representative told MailOnline: 'Katie has always been tiny and she's recently been enjoying going to the gym more and getting herself into a routine with exercise etc which has beneficial for her overall well being.' 

As well as modelling the dress, she also posed in a black sports bra as she gave fans a 50 per cent off code for beauty and collagen brand Rejuven 8 after bragging she is making 'millions' despite her bankruptcy.

It was no less than Katie's ex Carl Woods to confirm the star is currently filming for her IVF documentary earlier this month.

The Celebrity Big Brother sensation previously allowed cameras to follow her journey of having a baby with ex Carl Woods, 35, before they split in 2023.

Carl told Closer magazine he and Katie chose a surrogate together, who suggested they go to Cyprus to give it a go, before they split.

And now, judging from their recent trip to Cyprus, insiders believe Katie's recent trip to the island with boyfriend JJ Slater was a 'top secret baby-making mission'.  

According to Closer, a source said: 'Katie and JJ met with IVF clinic experts who have told her she does have a chance to have children - despite her lower-grade eggs and age.

'She has exhausted all IVF attempts and channels in the UK, and is hoping this is the start to expanding her family.'

Carl said the model's current situation mimics his 'parrot fashion' but 'with a different dude'.

He said: 'I don't think she cares who she has a baby with, as long as she gets a baby. In that situation, it's not about who - it doesn't matter.

'It could be me, could be surrogate, could be JJ. As long as she gets a baby. To a degree, I'm sure she would treat any partner as a sperm donor, really.'

The fly on the wall documentary, which will reportedly air next year, will also feature all of Katie children but TV insiders have said JJ won't feature.

A source told The Mirror: 'We'll see Katie go on a tough - and unsuccessful - journey to become a mum again. 

'She faces lots of obstacles, ups and downs along the way. The programme will shine a light on the struggles women face while trying for a baby in their 40s.'

MailOnline has contacted Katie and Carl's reps and Channel 4 for comment. 

The OnlyFans star previously revealed to MailOnline that she has experienced three failed rounds of IVF in the past year, she said: 'My eggs are too old, I'll get a donor egg'.

Katie is already a proud mum to son Harvey, 22, with former footballer Dwight York, son Junior, 19, daughter Princess, 17, with her first husband Peter Andre, and son Jett, 10, and daughter Bunny, nine, with ex-husband Kieran Hayler.

The TV personality previously told Olivia Attwood on her podcast: 'People have got to realise it doesn't matter if I act young or if I look younger, your body is still 46, and your eggs get less and they get older and it's harder.'

Loose Women and Love Island star Olivia then asked: 'But you definitely want another one?' 

Katie replied: 'Or two. It's going to happen one way or the other. I don't know how or well and I will, I'll try.'
