X Factor star set to join the cast of Hollyoaks

You'll probably remember Becca most for that (extremely) ill-fated affair with her ex-student Justin. The affair took place while she was married to horrid Jake Dean, and ended when she dumped him and he falsely told the police she forced him to have sex with her aged 15. To cut a long story short, she ended up getting stabbed and killed in prison. An absolute shocker.

After leaving Hollyoaks, Ali played PC Sally Armstrong in The Bill. She also competed in the 2009 series of Strictly Come Dancing, coming third.

The most notable storyline of Hannah's was her suffering from anorexia nervosa and bulimia nervosa. This proved controversial and gained a lot of press attention, particularly when her friend Melissa became the first person in soap history to die as a result of an eating disorder.

Since leaving the soap, Emma has appeared in a number of shows – including Fresh Meat, Prisoners' Wives, and films American Violence and Hollywood Dirt.

Poor old Sarah Barnes had an absolute mare of a time when she plunged to her death after girlfriend Lydia Hart accidentally sabotaged her parachute (thinking it was Zoe Carpenter's).Before that, Sarah was involved in many high-profile storylines – such as the Craig and Jean-Paul relationship, Amy Barnes' pregnancies, and Kathy Barnes' affair with Rhys.

Since leaving the show, Loui appeared in a couple of films and also sings in a band called Verity.

Nicole was a school friend of Sarah and Hannah, and also was involved with Justin after his affair with Becca.

Since leaving the show, Ciara became a prolific voice-over artist, and appeared on the radio show The Famous Five, as well as various BBC Radio 4 dramas.

Poor old Max had an absolutely awful time on Hollyoaks. Aside from the fact that pretty much every member of his family died, he also got into a relationship with that absolute beast Clare Devine, which culminated in his unfortunate death on his wedding day. Poor O.B.

Since leaving the show, Matt wrote several short films for Channel 4, and also worked as a voiceover on ITV2.

Craig was one half of probably the best soap relationship OF ALL TIME - Craig and Jean Paul. We'd never been happier than we were when those two finally got together.

Since leaving the show, he's appeared in a few TV shows - such as the BBC's Moving On. He has also been in films - notably Pitch Perfect 3.

Louise first appeared on the show as Darren Osbourne's girlfriend, but then ended up getting married to Warren Fox, who killed her on her wedding day. What a mess.

Since leaving the show, Roxanne has appeared on a number of TV shows - most notably Game Of Thrones. She' also appeared in Lip Service and Eastenders.

Justin Burton was the second party of the aforementioned teacher - student affair with Becca. He left the show in 2009 (alive, miraculously), and was mentioned again in 2017 when Warren Fox called to say their rival Clare Devine was dead.

Chris appeared in Coronation Street as Tommy Duckworth after leaving Hollyoaks, and was also a runner up in Dancing On Ice. He also last year joined the cast of ITV show Girlfriends in a supporting role.

Twins Mel and Sophie were the older sisters of Justin Burton. Mel struggled with alcoholism, and they both ended up getting killed in the fire at The Dog. So neither of their Hollyoaks lives were particularly peachy.

Since leaving Hollyoaks, Cassie has had a baby and become a beauty correspondent for Cosmopolitan magazine. Connie has kept a fairly low profile, but has since starred in Crackanory - playing the role of Zoe Two.

O.B. strictly speaking isn't a noughties-only Hollyoaks character as he returned in 2017, but he was certainly one of the most iconic. He was the other half of the absolute dream team that is Max and O.B., and dated Mel Burton while on the show.

As well as his brief comeback on Hollyoaks, Darren established himself as a presenter - having since hosted the British Soap Awards spin-off show and The Gadget Show.
