Sharon Osbourne opens up on her husband Ozzy's health issues, which has caused the Black Sabbath singer to cancel recent appearances on the band’s reunion tour.

She says, “He’s doing so much better. He had sinusitis, which went to bronchitis and he said that he felt like he had the Pacific Ocean in his ear, and he couldn't hear properly - it’s been a nightmare. He had to cancel four shows, they’re all going to be rescheduled, we’re working on it now. To have a responsibility of performing with his band Black Sabbath, the crew, the fans, even the opening act, just sat at home like this - waiting, waiting, waiting - and he feels that huge responsibility. He feels guilty for being sick.”

She continues that he is on the mend and “he will be in Seattle on Saturday. He will be ready to rock!”

On the heels of their much-anticipated performances in North America, Australia, New Zealand and Europe, Black Sabbath will end the epic journey they began nearly five decades ago with another run of North American dates in fall 2016. These shows will follow a mix of summer headlining and festival performances throughout Europe.

The second run of North American dates kicks off August 17th at Jones Beach Amphitheater in New York and includes stops at the Hollywood Bowl in Los Angeles (where the band last performed a sold-out show on their wildly successful 13 world tour in 2014), Chicago, Philadelphia, Toronto, Detroit, and Dallas, among others, before wrapping September 21st at AK-Chin Pavilion in Phoenix, AZ.

The massive 2016 world tour by the greatest Metal Band of all time marks The End for Ozzy Osbourne, Tony Iommi and Geezer Butler as they close the final chapter in the final volume of the incredible Black Sabbath story with this tour. Black Sabbath's The End farewell tour promises to surpass all previous tours and will feature the band's most mesmerizing production ever. An updated video announcement can be found below.
