Who's in the House?
It started last night on Channel 5, and with lots of Irish interest from Brian Dowling, Jedward and Paddy Doherty from Gypsy Wedding, we run down the contestants.
Here are the ten contestants who went into the Celebrity Big Brother house last night:
The American Pie actress shot to fame playing Kevin's girlfriend Vicky in the hit teen comedy.
A former child star, she failed to build on the multimillion- dollar success of American Pie and appeared in a series of flops and straight-to-video movies.
Her high-profile party lifestyle and some botched plastic surgery kept her in the headlines but left her, in her words, looking like she had been "butchered".
Only last week she announced she was engaged and then married to a businessman, Zack Kehayov, after a ceremony in Greece.
From: Los Angeles.
Most memorable moment to date: Accidentally flashing the world after a wardrobe malfunction on the red carpet at P Diddy's birthday bash.
The wife of House of Commons Speaker John Bercow infuriated her husband's political critics even before she entered the house.
They said Labour-supporting Sally had too much influence over her husband, who was first elected as a Conservative before becoming Speaker.
She did not help matters by giving a frank interview to the Evening Standard telling a reporter how "sexy" it was to live within the sound of Big Ben and posing for a photograph wrapped in a bed sheet.
The mother-of-three will be missed by her almost 30,000 followers on Twitter.
Most memorable moment to date: Her bed sheet photo shoot scandal.
The twins, real names John and Edward Grimes, were launched to fame on the back of their appearances on the 2009 series of The X Factor.
Their gravity-defying quiffs, energetic dance routines and enthusiastic attempts at singing made them legions of fans - and almost as many enemies.
But they have carried on regardless, carrying our hopes in this year's Eurovision Song Contest and continuing their career under the watchful eye of their X Factor mentor, Louis Walsh.
From: Lucan, Dublin.
Most memorable moment to date: Making a series of YouTube videos showing them performing duets after inhaling helium.
The reality show veteran has had her share of highs and lows since she first found fame as one third of Atomic Kitten.
From triumph in the jungle in I'm A Celebrity... Get Me Out Of Here! to the humiliation of bankruptcy and cocaine allegations, Kerry Katona has had a rollercoaster career in the public eye.
Her very public private life has seen her marry and divorce Westlife's Brian McFadden and she is currently estranged from second husband Mark Croft.
Most memorable moment to date: Slurring her way through an interview on This Morning in which she appeared disorientated and confused in the face of Phillip Schofield and Fern Britton's questioning.
The beautician has found fame through her appearances in ITV2's "structured reality" show The Only Way Is Essex. Her business Amy's Salon is at the heart of the series, as is her speciality treatment, vajazzling - which involved decorating her customers' intimate areas.
Childs, who is said to be planning her second boob job, now presents a beauty slot on ITV1's This Morning and hopes to open her own beauty schools.
Most memorable moment to date: Collecting a TV Bafta and shouting her catchphrase "Shuttup" from the stage.
Sabel is not exactly a household name but he has graced the catwalk in Milan, New York and Paris. Originally from London, he has appeared in ad campaigns for Levi's and Swatch and has been pictured by photographers such as Rankin.
Sabel has said he would rather be adored by all women than be tied down to one girlfriend.
Most memorable moment to date: Going on Celebrity Big Brother.
Australian-born "Mr Paparazzi" Lyons has been a war photographer and the boss of a huge picture agency as well as building his own TV profile.
Noted for his multi-coloured hairdos, Lyons starred in the TV series Paparazzi, which followed his company Big Pictures, and his various picture scoops have included shots of Diana, Princess Of Wales, Rudolf Nureyev and David Beckham. He was among the judges for a short-lived Australian version of Dragon's Den.
From: Geelong, Australia.
Most memorable moment to date: Appearing alongside Janet Street-Porter in celebrity reality show Deadline.
Pamela Bach Hasselhoff
The actress came to prominence on the sun, sea and skimpy swimsuit series Baywatch - a hit around the world - in the early 1990s, which also starred her former husband, David Hasselhoff. However she already had film roles under her belt including Rumble Fish, alongside Matt Dillon and Mickey Rourke.
The mother-of-two was married to Britain's Got Talent judge Hasselhoff for 16 years but they divorced in 2006. Jailed briefly last year for a drink-driving offence, she runs her own production company in the US.
From: Los Angeles.
Most memorable moment to date: Wearing a high-cut scarlet swimsuit and flicking her blonde mane.
Actor Laviscount is still in his teens but has already been associated with a number of established dramas. He has appeared in BBC1's Grange Hill and starred as Sophie Webster's love interest, Ben Richardson, in Coronation Street.
The young heartthrob has also modelled David Beckham's clothing and appeared in the Disney channel sketch show Life Bites.
His most recent role was as Jonah Kirby in BBC1 drama Waterloo Road.
From: Read, near Burnley.
Most memorable moment to date: His pupil character was seen having an affair with a Spanish teacher in Waterloo Road.
Irish traveller and born-again Christian Doherty appeared in documentary series My Big Fat Gypsy Wedding.
A former bare-knuckle fighter, he missed out on schooling and lives in a caravan park in Manchester.
During an appearance in a TV documentary, Deadliest Men, he bragged: "I'd bite your eyes and bite your lips off and I won't spit them out so you could sew them back on - I'd swallow them to disfigure you."
He says he rarely mixes with "townsfolk", and with his wife of 25 years he has five children and 15 grandchildren.
Most memorable moment to date: "Fessing up" during a court case earlier this year that his TV hardman bragging was "for the cameras... it was just having a laugh".
