The former The X Factor star and the The Vamps guitarist have been chosen to tackle the Christmas-themed Ding Dong Merrily Up High on Thursday evening’s instalment.
In the clip, Fleur can be seen dressed up as Santa Clause while James dons a Rudolph suit for the sky-high challenge.
It appears as though the trial will see Fleur guide James, who can’t see anything in his suit, along a bridge, way above the jungle trees.
James will also have to pick up Christmas presents that have stars on them, and throw them to Fleur who stands on an opposite bridge.
It’s not yet clear how the pair will do in the trial, and how many stars they’ll take back to camp.
Viewers will have to tune into Thursday evening’s edition of the show to find out whether or not the stars will be getting fed.
Meanwhile on I’m A Celeb, Anne Hegerty became the fifth evictee of the series on Wednesday evening.
The The Chase star revealed to Holly and Dec that she was surprised to have struggled so much, saying: “I’m much more of a wimp than I thought I was.
“I thought I would be strong and overcome my fears. I surprised myself by how, I actually found myself being more intolerant.”
I’m A Celebrity continues nightly on ITV.
