Earlier today it was confirmed by ITV that Gemma has walked from I'm A Celeb after just three days camping in the jungle.
Sad to see her go, Casey shared her reaction with her followers over Twitter.
She tweeted: "Can't believe @missgemcollins has quit @imacelebrity She was the best one in there! Gonna be pretty boring now."
And, she wasn't the only one to share her disappointment.
On hearing the news, many of Gemma's fellow TOWIE stars were shocked to hear about her exit - including Danielle Armstrong, Debbie Douglas and Lauren Goodger.
Celebrity Big Brother star Lauren said she "wished Gemma had stayed" and even compared her stint in the CBB compoud to being in the jungle.
After watching Gemma struggle with having no food, Lauren, although admitting the situation must be harder on I'm A Celeb, claimed she went without anything to eat for 12 days while in the house.
The reality star's exit comes just days after viewers watched Gemma suffer from a panic attack while getting into a helicopter on her way to the jungle.
Sent to the 'celebrity slammer', Gemma joined four other unlucky celebs in the jungle-style jail.
But, after being subject to food rations and sleeping on the jungle floor, it seems the experience all got a little too much for Gem.
Viewers will see Gemma leave the show on tonight's episode at 9pm on ITV.
