Toy Story actor Tom Hanks has sent a letter and a special typewriter as a gift to an eight-year-old Australian boy who said he was being bullied because of coronavirus.
The boy, whose name is Corona, first wrote to the Hollywood superstar when he heard the actor, who plays Woody, was ill with the virus.
Corona wrote: "I heard on the news you and your wife had caught the coronavirus. Are you OK?"
He said that he loved his name but was being called "coronavirus" at school, and that this made him "very sad and angry".
So Tom wrote back: "Dear Friend Corona. Your letter made my wife and I feel so wonderful!"
"Thank you for being such a good friend - friends make friends feel good when they are down."
"You are the only person I've ever known to have the name Corona - like the ring around the Sun, a crown."
He also asked Corona to use the typewriter to write back - perhaps the two will end up pen pals!
Tom Hanks isn't the only celeb doing good at this tricky time - good deeds range from giving money, streaming content for free, to buying food and face masks for hospital staff.
