Ozzy Osbourne is updating fans on his health struggles.

The Prince of Darkness surprised his fans at San Diego Comic-Con this weekend, where he promoted his upcoming record.

In an interview, he talked about being out in public saying, ”It’s great, it’s great. I like to see people, you know. That’s been the hardest thing of the past few years, because I’ve been trying to recover from my surgery. I’m getting there. It’s a slow climb back, you know?
