Irish contestant Marc O'Neill involved in 'fake' Big Brother eviction
Brian Belo has also joined Nikki Grahame and Helen Wood in the 'Big Brother' house.
The 27-year-old star - who was crowned winner of 'Big Brother' series eight in 2007 - has returned to the competition alongside Helen who won last year's series and Nikki who came in fifth place in 2006.
The trio of former housemates joined current contestant Marc O'Neill following his fake eviction from the show in the Timebomb bunker and Brian couldn't hide his glee at joining Marc in the underground room for the next 48 hours.
He told host Emma Willis: "He has got high energy and I am going to bounce off him and we are going to put a rocket up the house's a**e!"
However, there was one person Brian - who also described himself as "housemate viagra" during his entrance - was not looking forward to living in close quarters with.
He admitted, "I think I would least like to be stuck in the bunker with Helen Wood," shortly before the star, who is known for bedding footballer Wayne Rooney, joined him on the stage.
However, feisty Helen was quick to dismiss his fears and insisted she was planning on getting on with everybody in the house.
An excited Nikki, 33, was the final Timewarp housemate to enter the bunker and was heard shouting, "I'm s**tting myself" as she joined Emma on stage.
As the show came to an end Marc and the new housemates were given the secret task of choosing the nominees for the next eviction from the existing contestants.
