Carol Vorderman and Helen Flanagan set to take on terrifying trials in I'm A Celebrity All Stars

The I'm A Celebrity... Get Me Out Of Here! All Stars is set to begin in two weeks time. 

And Carol Vorderman and Helen Flanagan are set to take on terrifying trials in the upcoming show as a new trailer shows the countdown host facing a bungy jump.  

In clip, the presenter, 62, is seen suspended hundreds of metres in the air before it cuts to Helen as she makes her way across inflatable balls, also hanging in the sky.

Before entering the jungle for the second time, Carol admitted that her worst challenge was 'walking the plank' during her stint in 2016, so it could prove scary. 

Elsewhere, former Coronation Street actress Helen, 32, is seen throwing herself into the challenge as she bounces across balls to reach the stars.
