Pop star Fleur East and Huddersfield's own global sensation have enjoyed a sing-a-long together.

The 2015 X-Factor runner-up met with Olivia Farnsworth, who has recently hit the headlines across the world thanks to her unique medical condition.

The seven-year-old, from Crosland Moor, has amazed doctors after it was found she cannot feel pain, doesn't get hungry and has no natural ability to sleep.

A rare chromosome disorder means she could be the only person in the world with the three conditions together.

Everyone has 23 pairs of chromosomes but Olivia's sixth has a tiny piece missing.

The Examiner first revealed Olivia's rare condition in January.

Since then the story has gripped the world with it being reported on every continent.

Mum of five Niki, 33, hopes raising the profile of the rare condition will help researchers find treatments and she also wants to raise money for chromosome disorder charity Unique.
