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.

The superstar was dressed down for her Studio Sessions performance on July 12, wearing a bedazzled Willie Nelson T-shirt and flared jeans. After she belted out her 2015 bop "Dance with Me" early in the night, she took a moment to talk to the crowd and revealed that she was experiencing a bit of a wardrobe malfunction.
