TheUglyDollsstar confirmed the newsin a tweet on Thursday, explaining that she had “broken down in tears after the show from pain” and immediately flew back home once the awards show wrapped on Wednesday night.

Clarkson also shared that she had the surgery at Cedars-Sinai Medical Center in Los Angeles first thing on Thursday morning and was “feeling awesome” as she began her recovery.
