It was the grossest trial we've seen all series – perhaps since the very start of the whole show – as the TOWIE star was tasked with devouring a live, wriggling, rather large water spider.
VOM! Plus poor spider...
Like us, plenty of Twitter users first expressed total shock that anybody could be expected to eat a spider, let alone one that big, then confusion about how exactly one does eat a very fast moving spider, and whether this was a tad cruel for the poor spider just minding his own business.
Well, Ant & Dec had the answer to that: apparently you have to shake the cup holding the spider so that it balls its legs up together making it easier to get in your mouth and chew. Gross, gross, gross, gross, gross!
BUT SHE DID IT!
After some hesitation (understandably!) the Essex starlet faced her fears and gulped down the spider, giving us one of the most hard to watch moments of this series – spider legs sticking out of Ferne's mind as she tried to chew it up.
Even just remembering that moment makes us shiver.
As you'd expect, Ferne's TOWIE co-stars and fellow celebrities were quick to praise her for actually attempting the challenge, let alone completing it, with many saying that trial alone should have been enough to crown Ferne as Queen of the Jungle.

As you'd expect, not everyone was happy that a live spider was eaten for entertainment, with many viewers taking to Twitter to express disappointment in producers for selecting the trial.
