Kourtney Kardashian admits she drank an entire glass of her own BREAST MILK after feeling unwell as she becomes the latest star to follow the bizarre health trend

Kourtney Kardashian has sparked bewilderment among her fans by admitting she downed entire glass of her own breast milk.

No stranger to a quirky health trend, the Keeping Up With The Kardashians star confessed she indulged in the drink after feeling unwell for several hours.

Kourtney had been breastfeeding her baby son Rocky Thirteen, five months, and has spoken about been maximising her milk support by taking amaranth, barley, congees, millet, oats and rice, as well as bone broth, bone broth stews, kichari and congees.

Posting a selfie of herself lying in bed, Kourtney captioned her post: 'This filter is crazy and I just pounded a glass of breast milk because I feel sick. goodnight.'

Kourtney previously shared a snap of herself pumping breast milk in sexy black lingerie, after welcoming her son with husband Travis Barker last year.

The post sparked a mixed reaction from viewers, with some questioning why she would share a photo of herself 'pumping breast milk.'

The star also previously gave insight into her post-baby health regime, returning to the gym for the first time seven weeks after her son was born.

Kourtney wrote over the video that she was 'doing the most important job in the world…being a mommy: keeping my body alive, on demand breastfeeding means keeping calories high with lots of nourishing foods.' 

She noted she was 'taking time to slowly ease back into some uphill walks on the treadmill when I can sneak them in, along with my walks outside in the stroller.'

Kourtney is far from the first big name to try drinking breast milk, with Brody Jenner admitting last year he uses it in his morning coffee.

The Hills alum shared a clip of himself making a cup of coffee for himself and his fiancée Tia Blanco, with the unconventional ingredient as creamer. 

In a new YouTube video, Brody discovered he had run out of almond milk while making the lattes, but found that breast milk made for an amazing alternative.

Serena Williams also revealed in December she donated some excess breast milk she had to mothers and babies in need.

She is one of many stars who have followed the bizarre health trend, with Ferne McCann also admitting she's tried her own breast milk

In October, UK reality star Ferne McCann also surprised Steph's Packed Lunch viewers when she appeared on the show to talk about her six-month-old daughter Finty and revealed she'd also tried her own breast milk. 

Ferne - who is also a doting mum to daughter Sunday, six, who she shares with her ex Arthur Collins - said her breast milk was like 'liquid gold'. 

She also revealed she was told by nurses to use it as a first aid remedy. 'Finty, when she was born, had a little bit of weeping eye, and the community midwives are like, 'Put a little bit of breast milk on',' the model explained. 

'If Lorri had a blister I would suggest squeezing a little bit onto the blister, it'd be healed in moments.' 

Bodybuilders are known to have tried drinking breast milk in a bid to build their biceps although experts have claimed drinking breast milk is safe only if it is from a partner.

This is because breast milk is a bodily fluid, meaning adults who drink it could put themselves at risk of infectious diseases such as cytomegalovirus, hepatitis B and C, human immunodeficiency virus, or syphilis. 

The U.S. Food and Drug Administration (FDA) also previously warned of the dangers of giving a baby breast milk from a source other than the child's mother.

'Risks for the baby include exposure to infectious diseases, including HIV, to chemical contaminants, such as some illegal drugs, and to a limited number of prescription drugs that might be in the human milk,' according to the FDA's website.

Also, the milk can become contaminated and unsafe to drink if it isn't handled and stored properly. Adults are also susceptible to the some of same risks if they're drinking someone else's breast milk.
