Just weeks after she had to endure the pain of a burst appendix, as she hosted the 2019 Billboard Music Awards in May, she faced another major health crisis during an on-camera chat with pal and fellow "The Voice" judge Blake Shelton.
"It was literally a week after my surgery (to remove her appendix), so I was freaking out," Kelly tells People.
"Blake was talking to me and all of a sudden, everything he said just went away and I had to grab his arm and I was like, 'Something is wrong!'"
"That was more painful than the appendicitis... I was hysterically laughing and crying at one point in the E.R. (emergency room), like, 'What is happening?' I'm great now. I'm totally great now."
Kelly hopes there are no more mid-show health issues as she prepares to launch her first chat show, "The Kelly Clarkson Show", next month (September 09).
