She sensationally quit last year after just 72hours – but Gemma Collins was still said to be desperate to give I’m A Celebrity another go in 2015.

However, her Aussie outback ambitions have now been thwarted: ITV producers have sensationally blocked her from participating.

And they’re citing medical grounds as the reason.

Yes, following the standard psychological screening that all potential contestants partake in, the former Towie star has been deemed “too vulnerable”.

And according to The Sun, she is pretty devastated by their decision.

“Gemma is gutted because she was desperate to give it another go,” a source told the paper.

“She’s in the best shape of her life but docs feared another repeat of last year’s early exit.

“Despite losing weight and brimming with confidence, they felt she still wasn’t strong enough to cope with the demands.

“ITV still want her to be involved with the show in some capacity. They think she’s TV gold.”

Gemma’s brief time in the Celebrity Jungle was characterised by ongoing – and usually totally irrational – fears relating to just about everything.

Indeed, at one point she believed she had contracted malaria and she was often filmed in floods of tears.

In a further blow, it is believed that Ms Collins actually turned down a place on the latest series of Celebrity Big Brother just so she could secure her place on I’m A Celeb.

With Louis Walsh already confirming he’s been chatting to producers about an appearance on the hit show, the potential I’m A Celebrity line-up for 2015 is already looking like one of the strongest yet.

Ant and Dec will, of course, front the show – and it will begin airing on an as-yet unconfirmed date next month.
