Nine-year-old Astrid, from Southport, stood up in front of a plane full of holiday-goers in a bid to spread the message and garner support for a little girl fighting cancer.In the video, posted on Twitter, the Voice Kids contestant is given the tannoy by a cabin crew member.
She then introduces herself and tells passengers that what she is about to do is “for Jess who is in her last couple of days of life”.
But it is what she does next that gets passengers clapping, as she bursts into song with a rendition of Amy Whinehouse’s Valerie.
Wearing a #roarforjess t-shirt the talented schoolgirl showed off her unique singing voice.
And when it gets to the chorus the crowd is keen to join in, clapping along in rhythm to the hit tune.
The performance was in support of a little girl called Jess, who has been bravely battling neuroblastoma – a form of cancer – for seven years.
“Whoever you know tag them and get Jess trending.”
The video of Astrid, who is described as “the youngest Jazz and Blues singer in the UK” has been viewed almost 8,000 times since it was posted.
