Celebrity Big Brother (British TV series) series 6

Celebrity Big Brother 2009, also known as Celebrity Big Brother 6, is the sixth series of Celebrity Big Brother. It was broadcast on Channel 4, launching on 2 January 2009 and running for 22 days until 23 January 2009. The launch show was watched by approximately 6.4 million people. Davina McCall returned as main presenter, with George Lamb as host of Big Brother's Little Brother, and Jack Whitehall as host of Big Brother's Big Mouth. The winner of this series was Ulrika Jonsson, with Terry Christian second.

This was the first series of Celebrity Big Brother to air since the racism controversy of 2007, during series 5, although Channel 4's sister channel E4 aired a similar spin-off in 2008, entitled Big Brother: Celebrity Hijack.

This series was the least watched Celebrity Big Brother series, averaging 3.3 million viewers; at the time of transmission, it was also the least watched series of any Big Brother in the UK (excluding spin-offs) until the tenth non-celebrity series pulled in 2.5 million. Despite the low viewership, the launch show was the most watched programme of 2009 on Channel 4, raking in 6 million viewers.

Ulrika and Coolio took part in Ultimate Big Brother in 2010. Coolio was removed within the first few days and Ulrika finished seventh on the final night.

The logo remains the same as the eye from Big Brother 9, except with the star located in the centre.

The sixth season was sponsored by bed retailer Dreams.

The house used was the one from Big Brother 2008 and was largely unchanged, aside from a few minor modifications. Some of the wall panels near the stairs were modified to include stars in them to go with the format of the series. As the housemates entered the house there was a welcome pack available for housemates to read. The floor pattern in the basic bedroom were changed from the red segment of the BB9 eye, to a sequence of stars, and the beds were larger and more comfortable than in BB9. There was also a sign saying "You don't have to be mad to live here....but it helps" on one of the walls. The bathroom was completely gold, leaving no blue decor. The showers were closed off to give the celebrities privacy, although there were microphones in the showers. The garden house walls are now mainly blue and the pool has been taken out. The jail is now larger and includes a bench and mirror. A new heated sitting area was put in place and there appeared to be no spa or pool replacement. The smoking area, which contained a wall with dolls' faces with no eyes on, was moved for protection against the elements. The living area remained largely unchanged apart from some added weights and gym equipment. A specially designated entrance for housemate Verne was located to the side of the main door. This door does not have stairs.

Ben Adams (born 22 November 1981) is an English singer-songwriter, best known for being a member of the British-Norwegian boyband trio, a1. During his time, he developed a close friendship with fellow housemate, Michelle Heaton. On Day 22, Ben had been evicted from the house with 15.2% of the public vote to win, finishing in fifth place.
