Celebrity Big Brother 2006, also known as Celebrity Big Brother 4, was the fourth series of the British reality television series Celebrity Big Brother. It was hosted by Davina McCall and was broadcast on Channel 4 from 5 January 2006 until 27 January 2006, running for three weeks. By the time of the series finale, six housemates remained in the house. This was a first in Big Brother UK history and the next non-celebrity series, Big Brother 7, also adopted this format. Houghton was voted the winner on Finale night and was awarded £25,000 for her victory.
