There's a reason why we ~idolise~ Selena Gomez and Louis Tomlinson and it's not just because they're beautiful, stylish, talented etc.
They are also really good humans and use their powerful influence to help others.
The singers have taken part in a charity called GuitarTown Kids that raises funds for childhood cancer research.
Louis and Sel attended an event at Los Angeles Children’s Hospital to sign personalised guitars that will be sold at a VIP auction event.
They were joined by loads of other celebs including Miley Cyrus, All American Rejects, Grace VanderWaal, China Anne McClain, R5, James Arthur, Charlie Puth and more.
So proud of our baes!
