Miley Cyrus sent her young fan, who was on her deathbed, a touching video message just an hour before her death.

According to Contactmusic, the 21-year-old pop star was the first celebrity that the 12-year-old Caley Camarillo, who was suffering from cystic fibrosis, had long been an admirer of, said the deceased girl's mother.

She had also had the chance to meet the 'Wrecking Ball' singer a few years ago during Cyrus' tour, the mum added.

When Cyrus learned that her fan didn't have much time, she recorded a video for her which was posted on Facebook by the sick girl's mother.

The girls' mum, Teresa, also mentioned that her daughter had the chance to watch the singer's video shortly before she passed away, which had made her smile, maybe for the very last time.

Cyrus later shared on Twitter that her Bangerz concert in Lisbon, Portugal was devoted to her young fan.
