Celebrity Big Brother 12

Celebrity Big Brother 12 was the twelfth series of the British reality television series Celebrity Big Brother. It launched on 22 August 2013, three days after the fourteenth regular series final, in two parts. The series ended after 23 days on 13 September 2013, with Charlotte Crosby being voted the winner of the series by the public. It continued to air on Channel 5 as part of a two-year contract with Endemol, which secured the show until 2014. It was the fifth celebrity series to air on Channel 5 and the eighth series of Big Brother to air on the broadcaster overall since they acquired the show.

This was the first celebrity edition to be hosted by Emma Willis. Willis continued to host ...Bit on the Side, alongside Rylan Clark and AJ Odudu.

The official new eye logo for the series was released on 1 August 2013. The new logo design followed the same pattern as for Big Brother 14, but with a new golden theme. The new icon featured the doors, drawers and wooden frame of the fourteenth civilian series' eye – but it was recoloured in gold and navy blue to give it a VIP feel to tie in with the 'posh' theme of the series. Unlike most Celebrity Big Brother eyes, this logo did not feature the "star" in the centre.

On 2 April 2013, Emma Willis was officially announced as the host of Celebrity Big Brother, after previous host Brian Dowling was removed. Willis also presented Celebrity Big Brother's Bit on the Side alongside Rylan Clark and AJ Odudu, who replaced Alice Levine and Jamie East from the fourteenth regular series.
