The Underdog: Josh Must Win flipped the script on reality TV when it arrived in March.

What the group didn't know was that four celebrities were pulling the strings behind the scenes, doing everything in their power to make the group's underdog group come out on top. Here's everything you need to know about The Underdog: Josh Must Win..

The Underdog: Josh Must Win premise

The Underdog: Josh Must Win saw a group of would-be reality stars heading to a luxury home, where they thought they were participating in a popularity contest TV show called The Favourite, hosted by Nick Grimshaw.

Secretly, our four celebrity panelists were hidden away in a nearby room. From their observation room, the group got to keep a close eye on the proceedings, where they did their best to try and influence the proceedings

From the observation desk, they assigned tasks, spoke to the housemates and revealed surprise format changes, making using their own experiences of reality TV to try and guarantee Josh's win... all while trying to keep up the facade of the fake show and keeping their involvement a secret!

At the end of each day in the house, the contestants were asked to vote for their most and least favorite housemate: every time Josh wasn't voted least favorite in the building, an extra £10,000 was added to the prize pot that all nine stars stood to share.

Throughout the series, the unwitting cast were subjected to a "public vote" which saw one of them bowing out. Except, there was never a real vote, the celebs were just sending one person home.
