Rylan Clark(02 of20)
Open Image ModalHated by Gary Barlow, loved by the public; Rylan went on to win 'Celebrity Big Brother' and now presents 'Big Brother's Bit On The Side'. However, he's probably best known for his blindingly white teeth and incredible crying face. (credit:PA)
Diana Vickers(03 of20)
Open Image ModalThe softly-spoken Vickers, who got to the semi-finals in 2008, has expanded away from music, starring in West End shows, releasing a fashion line and apparently working on a Clint Eastwood film.

Little Mix(05 of20)
Open Image ModalFrom four solo artists, to two separate girl groups, to Rhythmix, to Little Mix, the band didn't have the simplest start on 'The X Factor'.

Eoghan Quigg(06 of20)
Open Image ModalYes, him! Creator of what was reviewed as "the worst album in the history of recorded sound" by the Guardian's Peter Robinson, which tells you all you need to know about Quigg's career. Last seen with his top off, flexing his new muscles in celeb mags everywhere. (credit:PA)
Ella Henderson(07 of20)
Open Image ModalDespite being pipped to the top spot by James Arthur in 2012, Ella validated her title of 'the most talented performer in the show's history' (courtesy of Dermot O'Leary) with her debut single, Ghost, going straight to number 1 in June 2014. (credit:PA)

Andy Abraham(09 of20)
Open Image ModalOffered forth to Europe as our representative for Great British music in 2008 in the Eurovision Song Contest, the former bin man came, er, last. At least he got points. He's also released four albums, so he's ticking along nicely. (credit:WikiMedia:)
Matt Cardle(10 of20)
Open Image ModalMatt Cardle won X Factor in 2011, apparently. You wouldn't know it. After his first successful single, Cardle's second peaked at a lofty 185 in the singles chart and he subsequently released two albums that you've probably never heard of. He's now turned himself into a West End star, and is currently appearing in 'Memphis'. (credit:PA)
Ray Quinn(11 of20)
Open Image ModalQuinn somehow came second behind Leona Lewis, and has taken part in a string of musicals and, of course, pantomimes since appearing on the show in 2006 and won the All-Star series of 'Dancing On Ice' in 2014. (credit:PA)

Rhydian Roberts(13 of20)
Open Image ModalThis is the least scary picture of Rhydian we could find and he stills looks like he's piercing someone's soul with his eyes. Anyhow, Rhydian was probably the most successful gimmick act in X Factor history, and has gone on to appear in musicals, while recording four successful albums. (credit:PA)
Cher Lloyd(14 of20)
Open Image ModalFamed for on The X Factor for her strut, snarl and, erm, swag, Cher's debut single, Swagger Jagger, reached number 1 in the charts, despite receiving mostly negative reviews. She's also achieved success in the US and got married along the way. (credit:Getty Images)
Steve Brookstein(15 of20)
Open Image ModalCast your mind back to the first series of 'The X Factor', and see if you can remember Steve. He failed spectacularly to make an impact on music and has since claimed Simon Cowell is "killing music". Sour grapes, anyone? (credit:PA)
James Arthur(16 of20)
Open Image ModalAfter starting his post-X Factor career with a chart-topping single and successful album, things started to go downhill for James in 2013.After writing lyrics which referenced homophobia and terrorism, Twitter spats with comedian Frankie Boyle and a number of Twitter rants, James was (unsurprisingly) dropped from Simon Cowell's label in June 2014.

Chico(19 of20)
Open Image ModalAfter 'It's Chico Time' and 'It's England Time' (for the 2010 World Cup), surely Chico was destined for worldwide fame and fortune? Where can we find him if we need some more hits? Hosting webcam gaming sessions for Bingocams UK, apparently... (credit:PA)
