Rocker Ozzy Osbourne secretly drugged wife Sharon with hallucinogenic narcotics, she has alleged.

The reality TV star says when she was trying to give up drugs, her wild husband crushed up a variety of addictive chemicals - as he was determined that the pair keep on living the rock 'n' roll lifestyle - and put them in her food without her knowing.

She said it caused her to hallucinate and smash up the couple's family home, celebrity portal Femalefirst reports.

Sharon has made the shocking revelations in a new book "Sharon Osbourne: Unauthorised, Uncensored, Understood" by Sue Crawford.

Sharon revealed: "I couldn't control my emotions. It wasn't until months later that he told me he was putting drugs in the stew. It took me a while to get over that, you know."
