Talia Castellano, the 13-year-old girl who was made an honorary CoverGirl thanks to her make-up tutorials online, has sadly passed away.

The teen was featured on the Ellen DeGeneres show who spoke to her about her illness and her inspirational attitude towards life. She had amassed over 15 million views on her YouTube videos before her death.

Talia spoke to Ellen about her battle with neuroblastoma and told the talk show host she was recently diagnosed with pre-leukaemia.

Ellen asked the teenager: "I am inspired by people like yourself. I think there are a lot of people who go through a lot of struggling situations, and despite what the doctors have said and the cancer you're going through, how do you stay so positive?"

"When people ask me that, what do you want me to do, be depressed? I mean a little fishy told me, just keep swimming, just keep swimming!" Talia replied.

Ellen tweeted about how sad she was to hear of the news.
