Ozzy Osbourne's son Jack says that his father is “doing really well,” less than a month after health struggles forced the Black Sabbath singer to cancel all live appearances through the end of the year.

Jack was asked for an update on Ozzy's health status during an appearance on The Jenny McCarthy Show and replied, “He's doing really well. He's good. He's getting back on his feet, so he's good.”

In early April, Ozzy postponed all his 2019 tour dates, both in North America and Europe, as he recovered from an injury sustained while dealing with his recent bout of pneumonia. The singer fell at his Los Angeles home, aggravating years-old injuries from his 2003 ATV accident that required new surgery.

In a separate interview with People, Jack said about his father, “He's doing good. He's back to being his cynical old self, (which) is always a good sign. When he's complaining about mundane things, you know he's good. Yeah, he's back to normal.”

Most of the 2019 shows on what is being billed as Ozzy's last full world tour will be rescheduled beginning in February 2020. Fans are being asked to hold onto their original tickets, as they will be honored for the rescheduled dates.
