Actress Maisie Williams is best known for her portrayal of badass Arya Stark on Game of Thrones.
The 18-year old is also going to be making an appearance in another fan-favourite TV series Doctor Who.
While she seems to be keeping pretty busy with her acting career, she’s also not one to forget her friends from before she was famous.
The teenager has donated €13,000 to a charity set up by her friend from school with cancer.
According to the Bath Chronicle, the Game of Thrones star, donated the money to Willberry Wonder Pony Charity after winning it on a radio show.
The charity was set up by 17-year-old Hannah Francis who is a pupil at Norton Hill School in Midsomer Norton.
Maisie and Hannah know each other from school and when Maisie heard about the charity fund, she was keen to do whatever she could to help out.
Hannah, who is a talented horse rider, developed osteosarcoma, an aggressive form of bone cancer earlier this year.
While undergoing treatment, she has turned her fight against cancer into a mission to #KickCancersButt. She’s also turned her mascot Willberry the Wonder pony into a global force against cancer.
Maisie won the money after appearing on Absolute Radio's 'Who's calling Christian?'

She took the top prize after being voted the winner of best phone call, beating the likes of Sir Bruce Forsyth, Jim Carter and Sharon Osbourne.
Currently filming the next series of Game of Thrones, she told the station how the two girls met and how Hannah had started the charity.

Maisie told listeners: "It is a heart breaking story but Hannah is doing really well."
A social media favourite, Maisie also told listeners to follow Hannah's story on social media and through her own personal Twitter account.
The Willberry the Wonder Pony charity has raised around €55,000 and the money will be divided between cancer charities of Hannah's choice.
