The Internet fell in love with 13-year-old Talia Castellano, who is battling two agressive forms of cancer, through her expert makeup tutorials on YouTube and her always-positive attitude. This week, the inspiring young makeup artist's dreams of meeting someone she loves -- comedian Ellen Degeneres -- came true.
Talia, who enjoys experimenting with makeup as a way of expressing herself, shares that love with nearly 200,000 YouTube subscribers.
"I love and adore makeup, using it as my wig and having so much self-confidence to go out to the grocery store without a wig," she says in one of her videos. "It's just amazing."
Talia once mentioned in a video that it was her dream to meet Ellen Degeneres, and that dream became a reality when she made an appearance on "The Ellen Show" this week. Talia broke down in tears twice on the segment -- once when she met her idol, and again when Ellen gave her a big surprise. Ellen, a Cover Girl herself, made Talia an honorary Cover Girl, complete with her own portrait. Tallia was also given a CoverGirl makeup table and $20,000 from the makeup brand.
Watch the video above to see the priceless look on Talia's when Ellen gives her a big surprise, and head over to her YouTube channel to view the makeup tutorials that made her famous.
