London, April 9 (AZINS) Singer Ozzy Osbourne used to hide his drugs in the oven because his family can't cook, says daughter Kelly Osbourne.

The 66-year-old vocalist concealed his habit from wife Sharon and their children Aimee, Kelly and Jack and knew stashing his narcotics in the kitchen meant they would never be discovered, reports femalefirst.co.uk.

Asked if she would consider working on a cook book with her mother Sharon, Kelly said during a question-and-answer session on The Talk's Facebook page: "Absolutely not! There's a reason my dad hid his drugs in the oven, it's because none of us can cook."

Sharon and Kelly are "best friends" and love nothing more than sitting at home and watching movies.

Kelly added: We've never not been close. My mom has always been my best friend. My favourite thing to do with my mum is just get in bed, put our pajamas on and just watch movies (sic)."
