The series will start sometime in January, probably the early part.
From the Ch4. website:
"Celebrity Big Brother returns to Channel 4 this winter, with a new group of notable housemates ready to put themselves on display in Britain's most famous TV house.
After a break from viewers' screens, the daddy of reality shows returns for what could be the most unpredictable and unforgettable few weeks of the celebrities' lives.
How will housemates cope with giving up the trappings of a showbiz life for a communal bedroom and a shared bathroom? Will the famous faces be up to the tasks and challenges that Big Brother throws at them?
Presenter Davina McCall presides over the live launch night and evictions, but, as ever, the true power lies with viewers when it comes to deciding who stays and who goes. Further details will be announced nearer to transmission, with celebrity housemates announced on the day they enter the house."
