Jason Aldean performs in Carrie Underwood's A Capella performance

The country music star showed off her exceptional talent and poise as she performed “America the Beautiful” at president donald trumpinauguration held in the US Capitol Rotunda. However, the “American Idol” alum's moment in the spotlight was not without drama and subsequent online debate. The performance took an unexpected turn when an audio malfunction interrupted the instrumental track she was meant to play.

Undeterred, Carrie Underwood quickly adapted, mouthing to the crew, “I can just sing it,” before launching into a powerful a cappella version of the patriotic classic.

Her quick thinking and professionalism drew applause from the audience, which included President Trump, his family, and various political officials. Members of the Armed Forces Chorus and the United States Naval Academy Glee Club joined in, turning what could have been a disaster into a unifying and memorable moment.

Despite Underwood's graceful recovery, the performance sparked a wave of online discussion that was mostly critical.

Now a viral Instagram post humorously compared Vice President Kamal Harris's reaction to the famous “RuPaul's Drag Race All Stars” moment. The caption read: “Kamala Harris looks like Coco Montres ('Girl Find the Note') watching Carrie Underwood at today's chilling inauguration.”

However, not all responses were critical. Country music star Jason Aldean publicly defended Underwood during the performance “Fox and friends.”

“First of all, it's a hard song to do anyway, and if you have to sing to the song, that's what gives you the pitch reference of the song,” Aldean said. “For it not to be, for her to just say, 'Okay, listen, we're going.' It's a big step and it's a professional step on her part, so I think it was great.

Originally planned as an outdoor event, the inaugural event was moved indoors at the last minute due to cold weather in the forecast for Washington. This change forced Underwood to perform in a tighter space, which reportedly affected her experience.

Sources revealed that Underwood was “unhappy” with her performance, mainly due to the cramped environment and lack of a proper stage. Unlike the high-profile performances of previous inaugural headliners such as Beyoncé and Lady Gaga, Underwood found her set to be underwhelming, with minimal space and compromised acoustics.

“She felt like she was literally just in a room with people around her and a microphone,” an insider explained. “Her anxiety was high throughout the performance and she felt that she was not given the respect or admiration that previous performers had received.”

Underwood faced backlash when she accepted an invitation to perform at Trump's inauguration, but she remained unfazed by the criticism. A source close to the singer shared that Underwood is “very proud” of his decision and doesn't care what the naysayers say.

“She visibly gripped her microphone, feeling uncomfortable,” the source said. “But she held her own and told the audience, 'Sing along if you know the words', even though her displeasure was obvious.”

Underwood then reportedly added to her frustration as she felt that the lack of preparation and last-minute changes negatively affected her performance.

While Underwood's performance may not have gone as planned, she remains determined to deliver an unforgettable moment despite the obstacles. “While it wasn't perfect and wasn't what she wanted, the unique nature of it all made it stand out,” the source concluded.
