Make-a-wish Foundation helped a little girl that has an inoperable tumor to meet Beyonce. So beautiful, must see! I think this is the most amazing think about being so popular as those rock/ pop stars, only their presence can make such an effect on people's life!

Beyonce is really into it!

Although "Survivor" might not be the best song choice for a girl with an inoperable tumor. :(

Still, overall this is quite inspiring: "Since I'm here, I might as well live!"

Is there a website that talks about which celebrities go the extra mile like this?

It would be good to see which celebrities do this.

On make a Wish Foundation they have a few celebrities that helped kids' wish come true: http://wish.org/

I found this other website where people can tell their experience with some celebrities: http://celebritygooddeeds.com/
