Paula Hamilton and Heidi Montag and Spencer Pratt have been nominated for eviction alongside Frankie Dettori ahead of Wednesday night's (January 9) first departure from the house.
Jockey Dettori chose to put himself up for eviction yesterday (January 5) in a surprise twist. Dettori volunteered to go up for the public vote in return for a place in the main house.
Paula Hamilton was moved from the basement on Friday following medical advice, while The Hills stars Montag and Pratt also joined the main house yesterday.
The first housemate to be evicted from this year's series will be announced on Wednesday night's live eviction show with host Brian Dowling.
Celebrity Big Brother continues tonight at 9pm on Channel 5.
