It's not often you witness the softer side of Simon Cowell, but we reckon few people will just see him as the tough-as-nails music mogul after this amazing gesture.
Simon recorded a video message to encourage people to donate to the Just Giving fund for a four-year-old little boy, who has been diagnosed with an extremely rare form of Leukaemia.
The little boy's family are raising funds on a JustGiving page to take him to America after discovering a children's hospital could potentially save his life with a treatment called CAR-T.
His family have so far raised £350,000 out of the required £500,000 for the treatment - which is currently unavailable on the NHS - and now X Factor boss Simon has stepped in to help.
The little boy's mum shared the video of Simon making his appeal for other to donate on Facebook, and wrote underneath it:
"Thank you to Simon Cowell for doing such an amazing job at supporting our cause. I explained to [my son] that Simon has helped to pay for his special medicine. [He[ said 'thanks Si' lol little does he know exactly what this actually means and how much closer we really are to getting him to the US."
In the video, Simon says: "This boy is four years old and needs money to get him to America to get the help he needs. I want you please to go on [his] JustGiving page and whatever you can donate will make a difference."
"And because I don't like well-known people telling people to do something and don't do anything themselves, I'm going to donate £50,000. We're going to get there."
This isn't the first time Simon Cowell's charitable giving has hit the headlines though.
I'm going to donate £50,000. We're going to get there.
Back in September, he gave a whopping £25,000 to help UK charity Humane Society International rescue dogs from death row on South Korean dog meat farms.
Dog-lover Simon - who has three Yorkshire Terriers of his own, Squiddly, Diddly and Freddy - had spoken up on behalf of the charity in 2017, and called for the end of the dog mat trade.
Speaking to Good Morning Britain at the time, Simon said: "It's like eating your friend. It's the fact you're eating such a kind, helpless, sweet animal."
