Kelly Clarkson kicked off her Las Vegas residency's first show with an apology to fans after postponing opening night last week: 'I'm so sorry. We can't help our bodies sometimes.'

Kelly Clarkson kicked off her latest Las Vegas residency on Friday, July 11 — one week after she was forced to cancel two shows hours before the first was scheduled to begin to 'protect' her voice.

Backstreet's back, alright. You might have thought the Backstreet Boys peaked in the early 2000s, but fans dressed in all white leaving Las Vegas' Sphere Friday night (July 11) would disagree. The group of five arguably put on their best show yet in the high-tech venue right off the strip.
