This is some powerful stuff!
At a concert in Sydney this weekend, Beyonce picked a very special girl from the audience to come on stage with her as she sang the touching power ballad Halo.
Little Chelsea is suffering from Leukemia and the lyrics to the song took on a much deeper poignance as Beyonce sang them.
There was not a dry eye in the house!
Watch the very very very touching moment that has left us sobbing and teary-eyed mess (above).
P.S. Music can heal. It can!
