I'M A Celeb viewers spotted a 'mystery patch' on Sue Cleaver's arm during last night's show.
The actress - who plays Eileen Grimshaw in the ITV soap - is one of 12 famous faces currently living in the Australian jungle as part of the hit TV show.
Within the first five minutes of Wednesday evening's show, fans pointed out a patch on the Sue's arm.
It has left viewers divided, with one asking if anyone saw the nicotine patch on her arm.
They said on Twitter: "Anyone else notice Sue’s anti smoking patch? #ImACeleb."
However another pointed out that it's likely to be a Dexcom patch, which is used to help people with diabetes monitor their glucose levels.

They replied to their tweet with: "i think its a dexcom."
The Sun have contacted ITV for comment.
Sue Cleaver has type 2 diabetes, a serious condition where your pancreas can't make enough insulin, or the insulin it does make doesn't work properly.
Insulin is a hormone, that's essential for us to live. When we eat carbohydrates, they are broken down by the body and turned into glucose, which is the fuel our bodies need.
The pancreas then releases insulin, which acts as the key, allowing glucose to enter the cells in the body.
But, in people with type 2 diabetes, the insulin doesn't work properly, and the glucose can't enter the cells.
As a result, the glucose stays in your blood stream and your blood sugar levels keep rising, meaning more insulin is released.
It's vital that people with the condition - which makes up around 90 per cent of diabetes cases in the UK - monitor and control their blood sugar levels, so they can take medication or other interventions, if it is too high.

Over time, high blood sugar levels can cause complications including nerve damage, slow healing, heart disease, damage to the eyes and kidney disease.
That's where patches like the Dexcom monitor come in handy, allowing people to use their smartphones to scan the sensor, which is linked up to a very fine needle that sits just under the skin, to keep track of their glucose levels.
