Remember Hear'Say? They were all anyone could talk about in 2001 - after the members won their place in the band through reality show Popstars, Noel Sullivan, Danny Foster, Myleene Klass, Kym Marsh and Suzanne Shaw were seriously popular.
Although Hear'Say didn't exactly last long, the band went on to do big things on their own - especially Kym, who became a fan-favourite on Coronation Street as Michelle Connor.
Noel has also had an incredibly successful career, focusing more on theatre and the West End and starring in plenty of shows like Grease, Fame and We Will Rock You - and now he's turning his attention to School of Rock.
And in an appearance on This Morning today, Noel revealed that he'd put on two stone for the role, telling Ruth Langsford and Eamonn Holmes why it was important for him to do that, "In the script there’s a lot of talk about the teacher being fat. You can’t do it with a fat suit, it would look really weird. It’s live and you are right there. It’s a very physical show."
When asked whether he'd be losing the weight after finishing his run in the show, Noel said, "We will worry about it then. In the meantime it’s pizza and pasta for me!"

1 of 12Will Young
Will obviously beat Gareth Gates in the final and went on to release a string of massive singles including Light My Fire and Leave Right Now. He released a greatest hits album in 2009 and just missed out on a spot on The Voice UK panel to The Script's Danny O'Donoghue. In 2016 he joined Strictly Come Dancing; only to leave the show three weeks later due to 'personal reasons.' Will still makes music and will be releasing his book To Be A Gay Man in September 2020.

He was in a relationship with Coronation Street actress Faye Brookes from 2012 to 2019 before being linked to DJ Chloe McLennan in July 2020.
3 of 12Zoe Birkett
Zoe came fourth on the show and released a top twenty single (Treat Me Like a Lady, which reached number 12) before being dropped by Pop Idol creator Simon Fuller's label. In 2014 she entered Big Brother (not even the celebrity version) and came ninth.
4 of 12Korben Niblett
The first contestant to be eliminated from Pop Idol is also known as Chris Niblett. According to his LinkedIn profile, Korben's been a Regional Education Manager at Estee Lauder Travel since late 2014.

6 of 12Hayley Evetts
After finishing fifth, Hayley bagged a small role on Coronation Street and starred as Sandy in Grease alongside Robbie Williams' best mate Jonathan Wilkes.

7 of 12Rosie Ribbons
Rosie signed a five-album deal after coming sixth; releasing top twenty singles Blink and A Little Bit. After her record label went bust she was released from her contract, but Rosie did enter Australian Idol in 2007. Didn't make it through to the final 12, though.

12 of 12Jessica Garlick
She might've only finished ninth, but Jessica went on to represent the UK in the Eurovision Song Contest with Come Back. She even managed to come third, which is pretty bloody amazing.
Of stepping into Jack Black's shoes - who made the role famous in the 2003 film - Noel said, "It’s a tough one. People know the film, it’s an amazing part to play. The kids are the draw really. They are playing live every single show. They are 9 years old!
"We have three teams of 12 kids. Some of them have never been on stage before, they are amazing musicians, you watch them grow and become amazing performers."

But with the help of a diet plan, Jonathan was able to lose a whopping three stone in just 12 weeks, and six inches off his waist!
Of course, talk soon turned to Hear'Say, and how it impacted his life, "It was before the time of social media, we were just on everything. Every TV show, every radio show, you couldn’t pick up a paper without us being in there so because it was such an intense focused time, I think people think it was longer ago than it was."
He also revealed what he did after the band broke up, "I went back to Cardiff, I have amazing family and friends, and then I found my way into theatre, which was my first love. I think theatre stars work a lot harder.
"I’ve learnt a hell of a lot more about performing during my 15 years in the West End and on tours and the cast you get to work with are phenomenal talented and are doing it eight shows a week, not just three minutes."
