Kelly Clarkson had an eventful 24 hours after hosting the Billboard Music Awards in Las Vegas on May 1.

Kelly revealed via Twitter that immediately after the show she flew home to L.A. and underwent an appendectomy.

In addition to her hosting duties, Kelly also walked the red carpet, performed a medley to open the show and treated fans to a rendition of her new song, “Broken and Beautiful,” which is featured in the new UglyDolls movie—all while suffering from appendicitis.

Kelly tweeted, in part: “Not gonna lie….I may or may not have broken down in tears after the show from pain BUT thanks 2 all the amazing people @ Cedars-Sinai I flew home directly after the event, nailed the surgery early this morning, & feeling awesome now! Bye bye appendix #TheShowMustGoOn.”
