An influencer who quaffed her friend's breast milk confirmed it was 'good' and didn't 'taste like boob' - but aside from the ick factor, there's an important reason why you shouldn't do this.
Influencers are known for doing a whole host of weird and wild things to get attention.
From selling jars of their own farts to heading to the gym in nothing but body paint, there doesn't seem to be a limit to what they're willing to do.

But perhaps they should draw the line at swigging their mate's breast milk, as doctors advise you absolutely should not do that.
Prepare to feel queasy as you watch her do it below:
Nuria Blanco, 27, from Barcelona, is a lifestyle influencer with almost 400k followers across social media.

Earlier this month, she shared a bizarre video to TikTok captioned: "Trying the milk of my friend who just became a mother."
In the short clip, her friend can be seen pouring the milk into a glass, before Blanco takes a swig.
She then turns to the friend and says: "Girl, it's good, it doesn't taste like boob."

But, while Blanco seemed to enjoy the milk, the video left viewers in shock, with hundreds taking to the comments to share their opinions.
One person wrote: "What did my eyes just see?"
Another commented: "There's no way I'm doing that," while a third said: "I miss my life from 20 seconds ago."
And, a fourth joked: "I prefer to drink straight from the container."

As weird as it may be, Blanco isn't the only one drinking breast milk.
Earlier this year, Kourtney Kardashian admitted to drinking her own breast milk for one key reason.
Back in April, the reality TV star took to Instagram, posting a selfie on her Stories using one of the app's filters.

"This filter is crazy and I just pounded a glass of breast milk because I feel sick. goodnight," her caption read.
According to experts at Milkify, 'continuing to breastfeed (when feeling poorly) can provide benefits to both the mother and the baby,' so it turns out Kardashian's late night snack wasn't that bad of an idea.
However, they stated that 'rest and hydration' should be the priority for the mother, when feeling unwell.
The experts also advised to maintain a 'healthy diet,' full of fruits, vegetables, whole grains and lean protein.
But, while drinking your own breast milk does no harm, it can actually be really dangerous to drink someone else's.
Adults face the same dangers as babies if they consume someone else's breast milk, including potential 'exposure to infectious diseases, including HIV, and to chemical contaminants, such as some illegal drugs.'
Dr. Sharon Unger, a neonatologist at Mount Sinai Hospital in Toronto, Ontario, said in a 2011 Canadian Medical Association Journal article: "Sharing unprocessed breast milk is dangerous.
"There’s something in the mother-baby unit that protects babies from certain bacteria in their own mother’s milk, but with a stranger’s milk you just don’t know."
So it's definitely best to leave breast milk to between mother and baby.
