Just hours before she would have gone onstage, Kelly Clarkson was forced to postpone the start of her Las Vegas residency in order to “protect myself from doing serious damage,” she told fans on Friday.

The singer and daytime talk show host was scheduled to begin her Studio Sessions residency at The Colosseum at Caesars Palace on July 4th. However, hours before showtime Friday, Clarkson posted on social media that both of this weekend's opening gigs were off.
