After undergoing emergency surgery right after the show, Clarkson healed quickly and was back onscreen just a week later, filming live shows forThe Voice. But the superstar singer reveals pain struck again as the cameras rolled.

“Blake [Shelton]was talking to me and all of the sudden, everything he said just went away and I had to grab his arm and I was like, ‘Something is wrong.'”

And that something, she later learned, was a cyst bursting on her ovary. “That was more painful than the appendicitis,” she says. “It was literally a week after my surgery so I was freaking out!”

After another trip to a busy E.R. (“I was like, ‘Anyone a fan? can someone help me get a hospital room?’”) Clarkson now says all is well. But the random back-to-back health scares did throw her for a loop.

“I was hysterically laughing and crying at one point in the E.R. like ‘What is happening?’” she says. Thankfully, “I’m great now. I’m totally great now.”
