They were dubbed as the 'mini-me' version of S Club 7 when they hit the stage as teeny boppers.
S Club Juniors first assembled on reality TV two decades ago and were a group all in their early teens who went on to have a chart-topping career together. But now those teens are all in their 30s.
What are they up to these days?
We took a look at former members:
Rochelle Humes
Previously known as Rochelle Wiseman, she was one of the original members who has gone on to do great things.
The now 33-year-old joined the group, then went on to join The Saturdays once time with the S Club Juniors had disbanded.
She started dating fellow pop star Marvin Humes, who was part of JLS, and in 2012, the pair got married.
Rochelle broke into TV via kids show Smile in 2004, and has worked on other shows such a The Xtra Factor, Ninja Warrior and This Morning.
Frankie Bridge
Then-known as Frankie Sandford, she joined the The Saturdays after leaving the S Club.
She then married footballer Wayne Bridge and the pair have two children together. She is now thought to be worth more than £10 million.
The star appeared on Strictly Come Dancing in 2012 and is also a regular panellist on Loose Women. This year, she made her West End debut this year in 2:22 A Ghost Story.
Aaron Renfree
Aaron is still working with the A-listers, although now in a slightly different role.
He is now a dancer and an in-demand choreographer and has worked with the likes of Taylor Swift, Little Mix and Kylie Minogue.
He has also had an impressive West End career, appearing in the likes of Flashdance: The Musical and We Will Rock You.
Jay Asforis
Now known as Jay Perry, the 32 year old is known for his acting skills as much as his singing and dancing abilities.
He has starred in Hamilton - the West End's hottest ticket - as Thomas Jefferson and Alexander Hamilton.
He also fronted a series dedicated to the S Club Juniors where he hosts Instagram Live interviews with his former bandmates.
Stacey Franks
The 33-year-old - who was known as Stacey McClean in S Club Juniors - tried her hand at a second shot of fame when she appeared on X Factor in 2009.
She got through to the live shows but did not win the series.
Stacey later starred in G*Mania, a collection of former X Factor, Britain's Got Talent and Last Choir Standing favourites, who toured the UK.
She is now married to ex professional footballer Fraser Franks and they have a daughter together named Nellie.
Calvin Goldspink
Calvin kept his foot in the music world and is now a singer-songwriter who has travelled with his talents.
He travelled to the US to star in a remake of British drama Wild At Heart and has also appeared in a 2011 royal film William and Kate: Let Love Rule, a TV movie that aired in the US, playing Princess Kate's brother James.
He is married to designer Melissa Callabero and they became parents for the first time to baby Aya in 2020.
Daisy Shelvey
Daisy is now working as a makeup artist and married to footballer Jonjo Shelvey with the pair based in Newcastle.
They tied the knot in 2015 and have a daughter named Lola.
Daisy did not leave the world of music straight after S Club Junior though - she had a music career with band From Above, who reached the Boot Camp stage on X Factor, before becoming a sought-after make-up artist.
Hannah Richings
Hannah was the youngest member of S Club Juniors, joining the group when she was just 11, and is no longer in the spotlight at all.
She is now married and a mum to four children, most recently giving birth to a baby girl called Pippa.
