Ozzy Osbourne was spotted using a cane while walking with his wife, Sharon, and two of their children in Los Angeles on Sunday, nearly one month after having a "major operation." The 73-year-old rock star wore a black T-shirt and matching black slacks as he made his way down a set of stairs with his family following closely behind. Osbourne is "on the road to recovery" after requiring a medical procedure in June that his wife of 40 years described at the time as something that would "determine the rest of his life." Ozzy wore a pair of black and white sneakers, and walked with a black cane with a shiny gold handle.
