Carrie Underwood has remained silent since her performance at Donald Trump's inauguration, though a source revealed she's frustrated with the outcome.

Despite overcoming technical issues and delivering a strong performance, the event has caused tension with the "American Idol" camp due to the perceived political stance.

An insider stated that her silence suggests that things didn't go as expected, but refuted rumors of a "hissy fit," claiming she was simply frustrated. They also pointed out that the pitch for the performance was different from its actual execution.

They clarified that the event's move indoors, which resulted in a smaller guest list, was the primary cause of the difference.

The source said Underwood was frustrated by the indoor venue limiting the number of people she could bring. While proud of how she handled the situation, she was likely second-guessing whether it was worth it, especially given her desire to protect her private family life.

Reports of her frustration emerge as tensions rise ahead of her new role on "American Idol," premiering March 9. The show, known for its inclusivity, is concerned her performance at Trump's inauguration may alienate contestants and viewers.

A source told Daily Mail that her apparent political stance might make some feel uncomfortable, as it conflicts with the show's values.

The insider revealed there could be tension between Underwood and fellow judge Lionel Richie, who is very liberal and may clash with Underwood's views, particularly as he has never supported Trump.

Before Trump's inauguration, some wondered if Underwood's performance could jeopardize her status as a judge on "American Idol," which she won in Season Four.

A source informed The U.S. Sun that "Underwood's job is not in jeopardy" and there were "no talks of firing her." "She will continue her role as a judge."

The insider noted that Underwood's inauguration performance didn't "conflict with any of her Idol taping dates" and "is before this season airs, so it doesn't go against anything in her contract."

They said several producers didn't like her performance, which surprised them. Thus, they feared fan retaliation.

They said, "A lot of viewers are already speaking of a boycott, whether or not that's true or just noise will be seen after the ratings come in but the conversation it now brings Idol into is not what producers want. They don't want the show to get political, they want it to be an escape from that."

Underwood emphasized her joy in playing at Trump's inauguration after the announcement, even though she may be questioning her decision, per The Blast.

The country singer expressed her love for the country and honor in performing at the inauguration, calling it a historic event. She expressed her humility in responding to the call for unity and looking forward to the future.
