Things got off to a flying start. Shaun was the first celebrity to enter the doors and of course, Big Brother was up to his tricks instantly.
Shaun was given a secret task and it went horribly wrong from the get go.
He had to prove that he was the most nervous housemate of all time and had to do a series of things to 'calm the first night nerves.' Cute.
Shaun was also given the power of giving two killer nominations. Eagle eyed viewers think Big Brother let one nomination during the live feed last night. It looks like 3 more housemates are going in!
