Jack Osbourne breaks his silence on his dad, Ozzy Osbourne’s, death, one week after the rocker was laid to rest. The 39-year-old admits his heart is still ‘full of so much sadness and sorrow’ since his dad died suddenly of a heart attack in July. Jack also shared a tribute video that included Ozzy’s sweet moments with Jack’s four daughters, plus outtakes from their adventures together on TV.
