Kelly Osbourne has revealed that she will audition to play the role of her mum Sharon – for the film based on his dad’s life.

She even dismissed claims that Colin Farrell will play her dad Ozzy in the film.

“It’s been rumoured that Colin Farrell is playing my dad Ozzy in the film of his life, which my mum is producing. With the greatest respect, at 34 Colin’s just too old for the role!” the Mirror quoted her as saying in her weekly Closer magazine column.

“We need someone who’s about 18, and my mum and the film makers want to get an unknown actor. I’ll definitely audition to play my mum, though.

“I don’t know if I’ll get it, but Mum has always said that I should go for it because we’re so alike. But it’d be a bit weird having to make out with someone playing my dad!” she added.
