The past winners
We take a look back at past winners of the Channel 4 show.
Comedian Jack Dee won the first ever series of Celebrity Big Brother in 2001, which was in aid of Comic Relief.
He constantly rebelled against Big Brother, escaping on day two, running out to see his wife during Anthea Turner's eviction, and loosening a panel on the toilet roof in another bid to escape.
Jack made no secret of his desire to be voted out, pleading with the public to let him go, and dressing up in a tweed jacket and cap while holding his packed suitcase during each eviction.
His deadpan humour was a hit with viewers and he won the week-long fly-on-the-wall competition ahead of soap actress turned musical starClaire Sweeney and Boyzone star Keith Duffy.
Since the show, Jack has continued to be a successful comedian and TV star. He has toured the country with his stand-up and has also made a name for himself as a serious actor, particularly in the TV show The Deputy, where he played a political fixer alongside Warren Clarke. He has also performed in Yasmina Reza's play Art in the West End.
Mark Owen won the second series of CBB in 2002, beating Les Dennis and Melinda Messenger in the final.
After Take That split, Mark became the first of the band's ex-members to release a solo record but he was dropped by his record label in 1997 when his album bombed.
He had been out of the spotlight for several years when he decided to go into the house, and the move paid off when he emerged from the show as the runaway winner with nearly 80 per cent of the vote.
After leaving the house, Mark signed with another record label and scored a Top 5 hit with Four Minute Warning, but the success didn't last and he was dropped again.
Luckily for Mark, Take That reformed in 2006 and are currently enjoying huge success, having had two No 1 albums and sold out tours.
Mark 'Bez' Perry, the British dancer and percussionist from the Happy Mondays, won the third series in 2005, after the show was rested for three years.
Bez said he only took part in the show because he was bankrupt and needed to pay an outstanding tax bill with his appearance fee.
He was a hit with the public, leaving the house as winner with 54 per cent of the public vote, beating actress Brigitte Nielsen and Blazing Squad's Kenzie.
The series was 18 days long, compared to the previous two which were a week long, and also featured Germaine Greer, Jackie Stallone and John McCririck.
Though Bez was loved outside the house, he wasn't so popular with his housemates, and was the most nominated person in the house.
Bez now co-fronts his new band, Domino Bones, with members of Black Grape and Boo Radleys. He lives next to Happy Monday's Shaun Ryder in Padfield, Derbyshire, and the band reunited last year to go on tour.
He used his winnings to improve the engine of his black cab and in March 2008 he declared himself bankrupt for the second time.
Chantelle Houghton, an Essex-born promotions girl, won the fourth series of CBB in 2006 - even though she wasn't a celebrity.
She was the first person to enter the house and was given a secret mission to fool the other contestants into believing she was a real celebrity and singer with a girl band called Kandyfloss.
She won the task when they ranked her as more famous than Preston and Maggot.
Chantelle was nominated for eviction on Day 21, but was saved by the public and the other two nominees, George Galloway and Dennis Rodman, were both evicted.
Chantelle won the show with 56.4 per cent of the public vote, ahead of Michael Barrymore, and netted £25,000. She married fellow housemate Preston just months after the show, following a whirlwind romance, but they divorced ten months later.
She had lost weight, died her hair brunette and changed her clothes to fit in with the indie singer, but has since returned to bottle blonde and after getting breast implants, has reinvented herself as a glamour model.
Modelling, TV appearances, interviews, magazine deals and an autobiography have made her a millionaire, and ironically she is now more of a celebrity than many of her housemates.
Shilpa Shetty, a Bollywood actress, won the fifth series of Celebrity Big Brother in 2007.
The series made headlines throughout the world after Shilpa was perceived to be the victim of racist bullying by S Club 7 singer Jo O'Meara, model Danielle Lloyd and reality star Jade Goody.
The show attracted 40,000 complaints, the largest ever received, and police investigated the series.
Carphone Warehouse suspended its sponsorship of the show and the then Prime Minister Tony Blair condemned their actions after receiving a complaint from the Indian government. Ofcom found Channel 4 guilty of broadcasting potentially racist material, and forced them to make multiple apologies.
Shilpa has had much success since winning the show. Her film Life In A... Metro was the first Bollywood movie to premiere in Leicester Square.
She also attended receptions at the House of Commons and with the Queen, and turned down a role in EastEnders because she was too busy to commit.
Shilpa has starred in several musicals and has also published a cookery book titled Soul Curry.
