Kelly Osbourne is set to play her mother Sharon in a TV movie.

She will star in the role about her mother's early years with husband Ozzy reports Femalefirst.co.uk.

Sharon has been secretly working on the project over the past few years but fears she will be forced to delay filming because she hasn't found anyone worthy of playing ex-Black Sabbath star Ozzy.

She said: "It has great potential but it will be hard to cast someone to play Ozzy.

"He is rather unique, you see, and it will take a big man to fill those shoes."
