Ozzy Osbourne's wife hurt herself while bending down and was receiving physical therapy for the injury, but the treatment didn't work and she had to get a surgery, reported E! online.
"You might be wondering where Mrs. O has been for the past week," Osbourne's "The Talk" co-host Julie Chen said.
"She is right now undergoing surgery..."
The 64-year-old star's daughter Kelly has been by her side and released a video from the hospital to update fans on her condition.
"She's doing really well. I just want to thank... Everyone for their support and thank the hospital because they've been doing such amazing work... And trust me she'll be fine.
