A week after KELLY CLARKSON hosted the "Billboard Music Awards" with a burst appendix, she was doing a live episode of "The Voice" when an ovarian cyst burst.

 Remember when KELLY CLARKSON's appendix burst on LIVE TV, while she was hosting the "Billboard Music Awards" in May?

You didn't know it at the time, because she sucked it up, finished the gig, and got her appendix out AFTER the show.  Sounds pretty bad-ass, but apparently, it was just another day at the office for Kelly.

Because a week later, she was doing a live episode of "The Voice", when a cyst on her ovaries burst.  And once again, she fought through it.  (Texas girls, amirite???)

She says, quote, "I had to grab [Blake Shelton's] arm and I was like, 'Something is wrong.'  That was more painful than the appendicitis."

So, after her second trip to the hospital in a week, everything was patched up, and she's totally fine now.  But she says, quote, "I was hysterically laughing and crying at one point in the E.R. like 'What is happening?'"
