It's a new year on Channel 5, and that can only mean one thing - the return of Celebrity Big Brother. Emma Willis is back to host the fly-on-the-wall fun, revealing the fresh group of famous personalities who will have their every word and move recorded for the enjoyment of the viewing public. This year, the first group of residents will all be women, to mark the 100th anniversary of women over 30 being given the vote, and will initially explore how the all-female housemates interact in a man-free zone.
