Although most of the stars in this year's I'm A Celebrity... Get Me Out Of Here! probably aren't used to packing light, that's the protocol for heading into the jungle.
After saying their final goodbyes to their loved ones and making it through an 'FBI-like' entry process, the campmates are sent off into the wilderness with the bare minimum.
The glitz and glam of their everyday lives is long gone and we see an extremely stripped back version of the stars during their time on the hit ITV show, which is hosted by Ant and Dec.
Before we know it, we're watching respected household names argue over who's turn it is to empty the dunny before chowing down on animal bits to win stars in Bushtucker Trials. Class.

This is the epitome of entertainment to the British public - as it seems there is just something about watching celebrities struggle to survive without proper meals and mod cons which really amuses people.
Which is exactly why viewers were in uproar when they thought N-Dubz singer Tulisa had somehow snuck in prohibited items.
But it turns out that the 36-year-old musician didn't follow Dean McCullough's lead and smuggle teabags into the camp, as there was another explanation.
A lot of I'm A Celeb fans thought that Tulisa was wearing make-up, while others also had their suspicions that Jane Moore and Coleen Rooney were doing the same.

Longtime watchers will be well aware that beauty products are outright banned in the jungle, although some stars have tried to sneak in items in the past.
So, the mystery of how these women looked so well groomed after a few nights sleeping under the stars became quite the hot topic.
And during this debate, it became obvious that a lot of people seem to have forgotten about the power permanent make-up treatments, which are especially popular among famous faces.

Usually, a tattoo is used to create designs that resemble make-up like eye-liner, brows, and other permanent enhancements such as colours to the face, lips, and eyelids.
This is a bit of a loophole which allows VIPs to get around the jungle rules.
However, it turns out that contestants can also get special permission to allow them to bring their favourite products in.
Georgia 'Toff' Toffolo set this precedent during her I'm A Celeb stint in 2017, as she revealed that show bosses allowed her to use foundation due to a 'medical exemption'.2017 im a celeb winne

The former Made in Chelsea star explained she was allowed to cover her acne with make-up.
Speaking to The Sun shortly after winning the show seven years ago, Toff said: "I honestly wouldn’t have been able to look any of my campmates in the eye if I didn’t have my make-up on.
"When producers told me it was banned I broke down in tears and said, 'I can’t do this'. I’ve been to the doctor so much over the years.

"It’s a medical problem and I’ve been on strong tablets for six months trying to get rid of them.
"Show bosses agreed that, because it was a medical problem, I was allowed to put foundation on once a day in the morning.
"Some people don’t understand how badly it affects my confidence and upsets me."
So if campmates want to look their best in between the Bushtucker Trials, it seems a valid medical excuse or permanent make-up is the only way for it.
