US model Cami Li is the hot favourite to be evicted in a surprise Celebrity Big Brother eviction on Monday night.

Celebrity Big Brother announced today that Emma Willis and Rylan Clark would be live in the studio from 8pm on Channel 5 to present two special shows.

Initially the celebrities will receive letters from home, but hometime will be a lot closer than they think for an unsuspecting housemate as Emma will enter the house to show one of the remaining eight the door.

Online betting company Betfair said Cami Li was 6/4 favourite to be evicted tonight, with former pop star Kavana next at 5/2 then US blogger Perez Hilton at 5/1.
