Kelly Clarkson Cancels Las Vegas Residency Opening Night

What doesn’t kill Kelly Clarkson makes her stronger.

Just hours before she planned to kick off her Studio Sessions residency at Las Vegas’ Colosseum Theater at Caesars Palace July 4, the “Since U Been Gone” singer postponed her first two shows.

“We have been working 24/7 to make Studio Sessions the most intimate and extraordinary experience with and for my incredible fans,” Kelly wrote in a statement shared to Instagram July 4. “I am beyond grateful that you always show up for me and I am devastated to have to postpone tonight and tomorrow’s opening at Caesars.”

As for why the American Idol alum—who shares kids River, 11, and Remington “Remy” Alexander, 9, with ex-husband Brandon Blackstock—had to cancel the shows so last minute? Well, it seemed she was experiencing some vocal strain.

“The prep and rehearsals have taken a toll on my voice,” the statement continued. “I want the shows to be perfect for y’all and I need to protect myself from doing serious damage so I am taking this weekend and next week to rest up so that we can deliver what you all deserve. The show is truly incredible.”
