The American Idol alum explained how she changed the lyrics of the angsty tune - written in the wake of her 2020 split from Blackstock - to reflect more of where she is today."I've never rewritten a song more and I probably never will," the mother-of-two began. "I wrote this song with a lot of hope and projection for happiness and better than what was happening. And then, well, life set in and I had to change the lyrics. Everybody was like, 'Wait, why aren't you singing this song?' And I was like, 'Have you heard the lyrics?' That's fun. Embarrassing."
