Beyonce: sings "Halo" to little girl at show in Sydney

Not much makes me cry...ever, but this just brought tears to my eyes.  Perhaps it's having children that has made me so emotional whenever I hear or see something sad or touching involving little ones.  This little girl, suffering from leukemia, had a dream realized thanks to Beyonce.  This lady is truly a class act!  If the handing over of her spot light at the VMA's to Taylor Swift didn't convince you then this surely will!  Simply beautiful....
