Cancer Patient Who Shared Stage with Beyoncé Loses Battle

It was the heartwarming moment that touched the world. Beyoncé singing her song "Halo" to a young cancer patient she called her angel.

Chelsea Lee James, her hair wispy from chemotherapy, was in tears. That touching video was shot almost five years ago and became a YouTube favorite. But recently, Chelsea suffered a relapse. Sadly, the day after Easter, Chelsea lost her cancer battle. She was only 15.

Her mother Donna posted this on her facebook page: "RIP my baby girl.  You can rest, love u always, mummy."

One of Beyoncé's fans said it all in a tribute on her Twitter page that read,  "Thank you Beyonce for bringing light into her darkest hours."
