Big Brother's Little Brother returned for the celebrity series once again hosted by Dermot O'Leary, for the first time ever it was broadcast in a late night time-slot on Channel 4, however it was broadcast in its usual Sunday lunchtime slot.

On E4, live coverage from the house dominated its daily and nightly schedule, Nominations Uncut and Diary Room Uncut – which were both introduced during Big Brother 5 also returned to E4, as well as Big Brother's EFourum hosted by Russell Brand.

The titles for this series are nearly identical to Big Brother 5, but with a brown background, red iris, and a pupil.

Mark "Bez" Berry (born 18 April 1964) is a British dancer and percussionist formerly of the alternative rock band Happy Mondays, who was fourth to enter the house on Day 1.

On Day 18, Bez left the house as winner with 54% of the public vote, beating Brigitte and Kenzie.

The UK edition of car TV show, Pimp My Ride later 'pimped' it out for him which included painting it purple and installing a DVD player.

Brigitte Nielsen (born 15 July 1963) is a Danish actress, who entered the house last on Day 1.

This included a clip of John comparing her to a "cash machine" and implying that everything she did in the house was for money and to promote her lingerie collection.

Prior to entering the house, she had criticised the show claiming it was "as civilised as looking through the keyhole in your teenager's bedroom door".

Germaine voluntarily left the house stating bullying of Brigitte by the show's producers and the behaviour of her fellow housemates towards John as reasons.

She entered the house on Day 5, as part of the Mediaeval Task, in which she was referred to as "the Queen mother".

She was the cause of much conflict between her fellow housemates particularly with Lisa who likened her to the Bride of Frankenstein and told her she hoped that she choked on her eggs.

Her lack of day-to-day knowledge was much to the entertainment of her fellow housemates such as her not being able to open a bottle of wine or make tea.

He was accused of bullying Jackie when in the house and was heavily criticized by the media and interrogated by the show's presenter, Davina McCall, for jumping up and down with joy the moment her eviction was announced.

John McCririck (17 April 1940 – 5 July 2019) was a pundit for Channel 4 racing, he is best remembered by Big Brother fans for his protest over not receiving Diet Coke.

In 2010, he entered the house for a second time to take part in Ultimate Big Brother, where he became the first housemate to be evicted.

In 2015, as part of Big Brother 16's latest Timebomb twist, John returned to the house as a guest at Hotel BB.

Kenzie (born 6 January 1986) is an MC and rapper, best known for being a member of Blazin' Squad and Friday Hill.

He entered the house seventh on his 19th birthday, he was tipped to win Celebrity Big Brother, but finished in second place, he has also appeared in other reality shows including CelebAir.

Eight housemates entered on Launch Night, it was Kenzie's 19th birthday and he was given a party by Big Brother.

Big Brother asked the housemates to nominate on Day 14, these nominations were in vain, as the public were already voting, I'Anson received the fewest votes to win and during a children's party where housemates dressed as children's characters and played a game of hide and go seek, I'Anson dressed as Little Bo Peep was called to the Diary Room and told she was evicted and unable to say goodbye to the others.

The live final (aired on 23 January 2005) which saw Bez crowned the winner pulled in an average audience of 5.4 million viewers, whilst an overall average audience of 4.1 million viewers watched this series.
