Kelly Clarkson Thought She Had Cancer at the 2006 Grammy Awards

Kelly Clarkson received alarming news from her doctors on the morning of the 2006 Grammy Awards.

Clarkson opened up for the first time about her health scare that occurred when she was only 23 years old on Billboard’s Pop Shop Podcast earlier this week. She was prepared to attend the 2006 Grammys after she had been nominated for Best Female Pop Vocal Performance and Best Pop Vocal Album, and though she won both awards, she was battling a deep fear within the entire evening.

“Well, not many people know this — not to be a Debbie Downer — but I was told that morning that I had cancerous results for something. Here’s the horrible part: I went the whole day crying,” said Clarkson. “They redid my makeup like four times because I was like, ‘Wow, so young.’ I was just completely freaking out.

“Then when I won, I thought, ‘Oh my God. This is like God giving me one more thing before something horrible happens.'”

After she endured the emotional evening and accepted her awards, she went back to her doctor the next day only to find out that they had “mixed up” her results.

“And I was like, ‘Are you for real?!’ I was like, ‘You completely ruined my entire [experience].’ The first time for an artist…as a kid watching the Grammys, that was a big dream!” remembered Clarkson. “It was kind of the worst/greatest day. And the next day was also the worst/greatest day because I wanted to punch someone. I was like, ‘Who mixes up results? Why wouldn’t you test again?’

“It was very much a roller coaster ride, that day, for me. So, it’s kind of unfortunate, but a lot of the moments got stolen from that mishap. But hey, I didn’t have cancer!”

Clarkson said that she doesn’t like to tell this story because it’s “kind of a Debbie Downer,” but it’s truly what was happening behind the scenes.

“You think it would’ve been the greatest night ever for an artist,” Clarkson said. “And then it was like a joke, like, ‘This is my last hurrah!’ I was so dramatic about it because I was twenty-something and scared. It was so weird. I don’t even remember anything but being terrified.”
