Kelly Clarkson said rehearsals for her new Las Vegas residency have "taken a toll on my voice" so she postponed the July 4 opening of the show to avoid "doing serious damage." She told fans, "I am taking this weekend and next week to rest up so that we can deliver what you all deserve.

Kelly Clarkson postponed the first two dates of her Las Vegas residency just hours before the show was set to begin.

I am devastated to have to postpone tonight and tomorrow’s opening at Caesars. The prep and rehearsals have taken a toll on my voice,” she wrote in a statement shared on Instagram Friday.
