Ozzy Osbourne's sisters Jean Powell and Gillian Hemming were blindsided by the news of his death after they had just reunited with him a few weeks prior at his final Black Sabbath concert. "He was frail, but it still came as a shock," Powell, 85, told The Mirror on Wednesday, July 23. "He still had plans and things he wanted to do." Osbourne died at 76 years old on Tuesday, July 22, his family announced in a statement shared with Us Weekly.
