X FACTOR’s rarely seen child star Cassie Compton is unrecognisable 17 years after appearing on the show.

Cassie wowed the judges during her time on the show’s first ever series.

Simon Cowell’s singing competition first began back in September 2004 and Cassie was one of the first hopefuls to compete for a recording contract on Saturday nights.

Kate Thornton was the host back then before Dermot O’Leary picked up from series four.

The original judging panel consisted of Louis Walsh, Sharon Osbourne and Simon.

Cassie was part of the 16-24s category mentored by Sharon, and was booted off the competition in fifth place after losing in the sing-off to fellow category member Tabby Callaghan, while Steve Brookstein went on to be the first ever winner of The X Factor.

But a then 17-year-old Cassie returned to acting, and her credits have since included playing Francine Spencer in BBC One’s Call the Midwife, and roles in Casualty, Mr Selfridge.

She also went on to star in West End productions of Wicked and Les Misérables, as well as American Psycho at the Almeida and playing the lead of Julia in the UK tour of The Wedding Singer.

She recently shared a throwback photo on Instagram alongside the Osbourne family, inlcuding Sharon and Ozzy, writing: “My iPhoto ‘memories’ remembers this moment more than I do!

“What an introduction to this industry… 17 years later this photo is the f**king bomb. Ps: thanks @jackosbourne for holding my shaking hand that evening- I would have fallen over. My love to you all.”
