Carrie Underwood reportedly felt "annoyed" and lacked the same level of respect as Beyoncé and Lady Gaga after her performance at President Trump's inauguration. Facing backlash from LGBTQ fans, she struggled with a technical glitch during her a cappella performance. Sources close to the country singer revealed she had a "mini hissy fit" due to feeling cramped and uncomfortable on a limited stage compared to previous performers. Underwood's anxiety was high, and she believed she didn't receive the same admiration as other artists, leading to dissatisfaction with her performance.
