CoverGirl has paid tribute to its youngest ever star Talia Joy Castellano, who died yesterday aged 13 following a six year battle with cancer.
The beauty giant issued an official statement to its Twitter account reading: 'Talia Castellano was the meaning of a true COVERGIRL. Please join me in sending love and honoring her memory.'
It has also re-released an image of the teen's honorary CoverGirl poster, which was unveiled last September on the Ellen show. The photo has been updated with the caption 'In Loving Memory.'
It was Talia's popular YouTube make-up tutorials that saw her become a CoverGirl, following in the footsteps of stars including Drew Barrymore, Taylor Swift and Pink.
She received her professionally shot advert from Ellen DeGeneres - another representative of the cosmetics brand live on TV.

'I'm shaking I love you so much!' the 13-year-old exclaimed as she met with the chat show host, just a month after revealing that she was battling two cancers at the same time.
The news of Talia's death was announced via Facebook yesterday.
A message posted by her mother read: '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.'
Since the announcement dozens of fans have taken to Twitter to offer their condolences including Ellen DeGeneres, Miley Cyrus, Kendall Jenner and Justin Bieber.
Talia was first diagnosed with stage four neuroblastoma cancer, a tumor that develops from nerve tissue in infants and children, on Valentine's Day in 2007 when she was just seven years old.
Following chemotherapy, surgery and radiation she was cancer-free for one year but in September 2008 doctors found the disease had spread to a small lymph node near her heart.
For the next four years she received various treatments, but after periods of remission the cancer kept on returning to other parts of her body.

Last year, on one of her famous YouTube video, she revealed that she had neuroblastoma and leukemia at the same time.
Doctors suggested a bone marrow transplant as a possible remedy but Talia decided forgo another painful surgery and enjoy her remaining days.
Talk show star, Ellen DeGeneres, previously cited the youngster as an inspiration.
Talia told MailOnline that clothes also helped to lift her spirits and some of her favorite looks included 'preppy', 'rocker' and 'boho chic'
