YouTube lost one of its brightest and most inspirational stars on Tuesday. Talia Castellano, who had gained fame for her fearless attitude and inspirational positivity in her videos, passed away after her six year battle with cancer.

Nobody who knew Talia would say that she lost that battle. The 13-year-old was well known for her perky and bubbly personality despite living under a death sentence for almost half of her life.

"It is with a heavy heart that we share with all of you that Talia has earned her wings at 11:22am," read a message on her Facebook page, Angels for Talia. "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."

Talia would often make videos that would put her extensive cosmetics knowledge on display. She expertly showed others how to use bronzer, eyeliner, and eye shadow. Since the chemotherapy robbed Talia of her hair, she lived by the motto "Make Up Is My Wig."

Her videos soon became very popular on YouTube, and at the time of her death she had over 750,000 subscribers to her channel. Many of her videos had accumulated well over one million views by the time of her death.

"YouTube, and all the support that I get from everyone telling me that I'm inspiring and not to give up, it really makes you stop and think about how many people there are that love you... You're not there alone," Talia told Shira Lazar, co-founder of WhatsTrending, in August 2012.

Talia exhibited a large level of bravery during her bout with two different forms of cancer. She was initially diagnosed with neuroblastoma, and later on last year Talia also found out that she had prelukemia. In one video she released last year, the brave teen revealed that she had rejected a potentially life-saving bone marrow transplant so that she could "just live the time I have remaining."

"I've always been a really bubbly girl, and my mom always tells me to think about the positive," she told PEOPLE Magazine in 2012. "Even though cancer is a negative, horrible thing, there are positives. For people to see that there are kids that get cancer... it's just a true fact. Me putting a face on it makes a difference."

Talia Castellano was beloved by all who had heard her story. Upon news of her death, the hospital she was staying at, the Arnold Palmer Hospital for Children in Orlando, had to request that people stop calling them about Talia because they had become overwhelmed with inquiries about her.
