However, fans of the popluar reality competition show were left stunned by an early twist, as just hours after entering the Big Brother house three contestants were put forward for eviction.
This resulted in Emily being chosen to leave the house on the first day, in a move which will also see four new contestants added.
In this Big Brother 2025 guide, we'll break down all the best betting offers which you can use on the show, the latest winner odds and all the other important information which you need to know to maximise your viewing experince!
