Heartbroken. That's the only way to describe the feeling when we heard our favorite little beauty vlogger, Talia Joy Castellano, died on Tuesday at the too-too-young age of 13. The honorary CoverGirl absolutely bowled us over with her sharp, sassy YouTube makeup tutorials, which she posted under the slogan, "Makeup is my wig."

Talia's passion for makeup started at the ripe age of 7, when she was first diagnosed with stage-four neuroblastoma. She told the world (and we were all watching) that makeup was her way to feel beautiful -- all while undergoing rigorous treatment for her cancer.

The news of Talia's death was reported on her Facebook page, Angels for Talia.

‬#‎prayfortalia‬ It is with a heavy heart that we share with all of you that Talia has earned her wings at 11:22am. Please lift her beautiful soul, her beautiful light to heaven and please send your love and prayers to her family during this most difficult time. God speed little one, may you be free from pain and suffering, may your soul feel the light and love that you brought to so many of us on this Earth during the short time you were her with us. We will miss you more than you will ever know baby girl. ‬
