There's going to be a big shake up in the Big Brother house tonight. Channel 5 has confirmed that a 'familiar face' will return as part of the big twist, which will see four housemates be evicted and replaced by four new ones.
Amy and Sally, Chloe, Danny, Harriet, Kieran and Sarah are facing eviction, however they don't realise they face the public vote.
Some super fans the 'familar face' are hoping it will be an iconic ex-housemate like Nikki Grahame, but nothing has been confirmed.
Emma Willis says "Just when they were adjusting to life in the house, Big Brother is about to drop a whopper of a time bomb. I can't wait to see how the surprise mass eviction, some brand new housemates and a very familiar face go down."
The shake up comes as Aaron was evicted for "inappropriate behaviour" towards Joel.
