Ex-housemates confirmed for re-entry

"Nasty" Nick Bateman, Nikki Grahame and Brian Belo have all been confirmed as ex-housemates re-entering the Big Brother house this week.

Rumours had predicted that Nikki Grahame would make a guest appearance in the current series, but it has now been officially confirmed that a number of housemates from the past nine series will be going back into the house to perform memorable tasks as part of the tenth anniversary celebrations.

Nasty Nick from Big Brother 1 will commence proceedings on Monday, when he enters the house to take part in an assault course. He will be followed by Dean from Big Brother 2 who will attempt to re-enact a record breaking challenge.

Monday will see a number of Big Brother 3 housemates take part in an egg-and-spoon race. On Tuesday, housemates from Big Brother 4, 5 and 6 will go back into the house.

Wednesday will see Nikki Grahame and Brian Belo take part in tasks from their respective years, before Big Brother 9's Rex Newmark challenges the housemates to a task on Thursday.

The culmination of the week-long birthday celebrations will climax on Friday with a live show, in which Davina McCall will reveal what other surprises Big Brother has planned for the anniversary.
