Sharon Osbourne has been dying her hair red for more than three decades - because she fears looking like "Ozzy's granny".

The X Factor judge turned to hair colouring when she was in her 20s, after discovering her locks were ageing prematurely.

And the now 54-year-old still refuses to let her natural hair colour show through.

She says, "It's s**t. Unbelievable that it happened so young. I can't just let my hair go white because I don't want to look like Ozzy's granny."
