India, Aug. 13 -- Kelly Clarkson stood under the stage lights, holding back tears. It was July 26, during her Las Vegas Studio Session residency, and a TikTok video from that night has now taken on new weight. Just 12 days later, her ex-husband, Brandon Blackstock, would be gone. According to People, the clip, shared by a fan present at her concert, shows Kelly, introducing a reworked version of her 2015 song Piece by Piece. She pauses mid-sentence, dabbing at her eyes. "Compartmentalization!" she half-laughed, half-pleaded with herself, trying to keep it together before diving into the story behind the changes. Kelly told the crowd she has never rewritten a track more than this one. The original version, released two years after marrying Brandon, was a pointed message to her estranged father, and a nod to Brandon as a better partner and father figure. That meaning shifted after their 2020 split. After a 2023 lyric change that addressed their divorce, she's now updated it again. Brandon died on August 7. A day before his death, Kelly postponed her remaining Vegas shows. HTC...
