In a cut scene from The Voice Season 26’s finale, Gwen Stefani walked off stage after fluffing lyrics during a performance.

The seasoned singer, who has been performing for decades, appeared extremely nervous before messing up her song during filming for the finale of the hit NBC singing competition show, which some fans dubbed “underwhelming.”

Stefani was also noticeably upset after having to stop her performance due to the blunder and even walked off stage for a minute to collect herself before they continued filming the episode.

Part one of the two-part finale, which aired Monday night, showcased the No Doubt singer’s finalist, Sydney Sterlace, 16, who sang two numbers.

While part two aired live on December 10, there were moments featured that were actually taped the previous day, a source at the studio told The U.S. Sun.

The 55-year-old pre-taped a duet with Sydney to the Cat Stevens classic, Wild World.

She wore a crystal-encrusted white and silver skirt and matching crop top with silver Christian Louboutin boots for the later cut performance.

Though it was not live, Stefani appeared noticeably “nervous” as she paced on the stage and even seemed to say a little prayer before take one began, the eyewitness claimed.

When she started performing, she allegedly needed to heavily rely on a teleprompter to sing the correct lyrics.

However, about 20 seconds into the song, Stefani stumbled with her timing and missed some of the lyrics.

She apologized to the crew as she halted the performance – forcing them to reset the lighting and stage pieces.

The singer appeared frustrated as she took a second to gather herself before returning to the stage.

Gwen Stefani’s performance on The Voice was cut

“Though it was relatively low-stakes given it’s pre-recorded, Gwen was very on edge and shaky at first.

“She looked really, really nervous before performing which most likely led to the mistake. She was able to recover well though,” the source added.

They even filmed the song a third time just in case, before Stefani, who looked elated, hugged Sydney before they walked off stage together.

The two bad takes were obviously not shown on part two of the finale, but fans were already upset by part one’s performances by the time it aired.

After part one, many viewers took to social media to slam the “underwhelming” first part.

Some didn’t hold back when they wrote online that it “sucked” because of the “monotone” performances from the finalists.

On Monday night, the five finalists, Danny Joseph, Jeremy Beloate, Shye, Sydney Sterlace and Sofronio Vasquez took to the stage for the last time to perform songs they thought would help them win the coveted $100,000 and recording contract.

Each artist performed twice during the episode, a ballad and an uptempo number.

However, some viewers weren’t impressed by the artists’ song choices.

Reacting to the finale performances, one person on Reddit started a new thread and wrote: “Just my opinion, but I’m really underwhelmed with the singers that are left as well as the song choices for the finale.”

One fans responded: “The lineup itself is great, it’s just that none of them performed up to their usual standard except Shye and Sofronio.”

Another agreed: “Same, nobody really wowed me tonight,” as someone else penned: “I’ve only been loosely keeping up with this season but every time I’m watching I’m like ‘This is what we’re left with?'”

Meanwhile, fans on X, formerly known as Twitter, were also quick to slam part one of the season finale.

“#TheVoice What is going on? Everyone sounds so weak tonight. Honestly, Shye ruined that song. Her voice was so monotone and weak. This season’s final sucks so far,” wrote one.

Another added: “Everyone has not done well!!!!! Love Sofronio though. He’s doing great,” as a third person said: “The voice is so cringe now … these finalists are extremly underwhelming #TheVoice.”
