Big Brother is undoubtedly the most famous TV show of the noughties - although its move from 'prime time' TV might have dampened its prospects in the last few years, Big Brother was the biggest show of its time.
Beginning back in 2000, channelling George Orwell's concept of 'Big Brother', the all-seeing 24/7 reality show was a new format that paved the way for all of the reality shows, like TOWIE and Made In Chelsea, that are plastered all over our screens today.
Although it might seem overdone now, 16 years ago this was something no one had ever seen before - members of the public living in a house together, having their every moment recorded and put on live TV.
It was also the beginning of some of our most-loved celebrity faces - where would we be without Alison Hammond, Imogen Thomas or the late Jade Goody?
ITV has confirmed Big Brother is returning for 2023 (opens in new tab).
We decided to look back at all the best house mates, and see what they've been getting up to since leaving that famous house...
1. Anthony Hutton
Series 6 Big Brother winner Anthony, who won over the public with his cheeky chappy personality, look so different now! He shared a recent picture of him looking very toned, while enjoying the sun on a lads holiday. After a short-lived media career Anthony went back to doing what he did best before he entered the house - hairdressing. He has opened a barbers shop in County Durham, which is also a bar.
2. Sophie Reade

Cast your mind back, and you'll remember Sophie as the winner of series 10 of Big Brother, taking the crown despite having to legally change her name by deed poll to Dogface to become a housemate in the first place...
She went on to have a successful career as a glamour model, but now her social media profiles say that she's 'retired' from a life in front of the camera. She's now a make-up artist and beauty therapist, who juggles work with taking care of her young son.
3. Ziggy Lichman

One half of the 'Posh and Becks of the Big Brother house', along with fellow contestant Chanelle Hayes, you probably remember Ziggy from series 8 of Big Brother.
Since leaving the house, Ziggy, real name Zachary Lichman, has appeared in the Channel 4 series Dead Set, and carved out a career as a celebrity talent manager, working with actor Lucien Laviscount.
4. Brian Belo
Everybody remembers Brian for putting Basildon, Essex, on the map and claiming to have never heard of Shakespeare before. Since the programme, Brian has become a columnist for Heat magazine, and starred in TV shows such as Harry Hill's TV Burp and Big Brother's Big Mouth. He also briefly dated Samantha - one half of Big Brother's Samanda.
5. Grace Adams-Short
Grace Adams-Short was a dance teacher from London who was evicted from the house early on as one of the 'most hated house mates of all time' but allowed to re-enter on her 21st birthday for 21 minutes, which saw her reunite with her Big Brother lover Mikey Dalton. After leaving the house Grace and Mikey stayed together, married in Plymouth in 2009 and had two children, Spencer and Georgiana! Who knew that the house was so good for long-term love?
6. Kate Lawler
Kate Lawler was the first ever female winner of Big Brother back in 2002 in the third series, after Brian Dowling's win the previous year. Kate has now moved away from the world of reality TV and made a serious name for herself as a radio DJ, including on Capital FM. She then moved to Kerrang and announced in March 2016 on her Twitter page that she has now joined Virgin radio as a DJ.
7. Nikki Grahame
Nikki was without a doubt one of the most dramatic house mates with her well documented temper tantrums in The Diary Room. Nikki won a National Television Award for Most Popular TV Contender in 2006 then went on to star in a series of advertisements for Domino's Pizza.
In 2007, Nikki had a regular column for OK! magazine. In 2014 she briefly moved to France to get away from the negative media attention but told Closer! magazine she returned in 2015.
8. Pete Bennett
Pete Bennett was the unlikely winner of the seventh series of Big Brother in 2004. Suffering with Tourette syndrome, Pete's quirky behaviour won over the hearts of the public and voters. Pete moved into singing and working for Greenpeace for several years after leaving the house. In April 2015 Pete appeared on the Jeremy Kyle show admitting he had spent all his win money and was now homeless and battling drug addiction.
Amanda and Samantha were the identical twins who entered the Big Brother house as one contestant - Samanda. Despite being bookies favourite to win, they only came as runners up in the show. Since leaving they have launched their own skincare range - Samanda by Young and Pure. They have also released music, including a cover of Aqua's Barbie Girl.
10. Brian Dowling
Brian won the second series of Big Brother back in 2001. He went on to enjoy a TV career, becoming the UK's first ever openly gay TV presenter when he took the helm at children's morning show SMTV Live. Brian then presented Big Brother between 2011-2013 until Emma Willis took over.
11. Chantelle Houghton
Chantelle was another contestant who hasn't really left the limelight for long in the decade since winning Celebrity Big Brother 2006. She was the first non-celebrity to be sent into the house and quickly struck up a romantic relationship with Ordinary Boy's singer Preston. The pair married after leaving the show but divorced 11 months later. They both re-entered the CBB house in 'Ultimate Big Brother' in 2010 and made it clear they were still friends. Chantelle now models and has a daughter, Dolly, with cage fighter and Katie Price's ex-husband Alex Reid. The pair have split since the birth of their daughter.
12. Aisleyne Horgan-Wallace
Aisleyne finished third in the 2006 series of Big Brother, losing out to Pete Bennett and Glyn Wise. Since leaving the house Aisleyne has made frequent TV appearances on panel shows and comedy sketches, including Charlie Brooker's show, The Friday Night Project and The Kevin Bishop show. She also wrote an Agony Aunt column for More magazine. She was at one time engaged to boxer Mike Tyson.
13. Nadia Almada
Nadia, born Jorge Leodoro, was the first transgender winner of Big Brother back in 2004. Nadia went on to record a single 'A Little Bit of Action', which reached Number 27 in the charts. Nadia also made a guest appearance in Hollyoaks to turn on the Christmas lights.
14. Glyn Wise
Glyn from North Wales won over the hearts of the population with his country charm, but was beaten to poll position by house mate Pete Bennett at the last minute. While we all remember Glyn as a loveable lifeguard, he has more serious aspirations and has gone into the world of politics. He even stood as Plaid Cymru's candidate in Cardiff Central.
16. Rachel Rice
Rachel is one of the lesser known contestants since the show, but she was actually a winner in series nine! A Welsh model, Rachel was runner up in a 2003 Miss Wales contest, which was won by Imogen Thomas who also appeared in Big Brother. Since returning to the valleys she has been modelling and living a life out of the limelight.
