I'm A Celebrity... Get Me Out Of Here is once again changing things up with a brand new format called Rivals. Ant and Dec entered the camp at the end of tonight's show to announce the big change to campmates.

The celebrities will have to take part in a series called Rivals, one-on-one, head-to-head trials and challenges.

The camp is split into two groups, and viewers have to vote for someone from group one to be paired with someone from group two. Over two days, the rival pairs will face challenges. The trials will decide who is up for the first elimination.

Another consequence is the six losing stars will also be sent to a different, and more basic camp. Not only will they be sleeping on the floor, they'll also miss out on the nicer food, instead having to stick to rice and beans.

Elsewhere in the show tonight, it was Jack Osbourne's turn to take on a solo Bushtucker Trial. But the reality star made light work of the trail, Down The Hatch.

Having to hold his breath, he had to dive down underwater and get stars out of submerged chambers full of jungle critters.

He completed one chamber in just 26 seconds, rather than the two minutes allocated, impressing Ant and Dec who dubbed him "a machine". He took back all 12 stars.

Campmates Kelly Brook, Eddie Kadi, Ruby Wax and Tom Read Wilson also took part in an evening challenge called The Jungle Nursery. After climbing in a large cot, they were showered with jungle critters as they had to describe children's stories to those back in camp.

They completed the challenge successfully and won a midnight feast of sweets for camp. But the sugary snack caused more issues than it should, when Ruby snuck off with a bag of liquorice all-sorts to enjoy for herself.

I'm a Celebrity… airs on ITV1 and ITVX.
