The Voice fans are trolling Gwen Stefani for her “unrecognizable” looks

Gwen Stefani was branded “unrecognizable” by fans for her dramatic new look on the latest episode of The Voice.

The 55-year-old singer returned to the show as a trainer during Monday's Battles round, but it was her hairstyle that stole the show.

The No Doubt star ditched her signature icy platinum strands and rocked warm blonde wavy locks with bold bangs that framed her face.

She paired the look with a bright yellow sunflower dress and gorgeous makeup.

Following the episode, fans flooded social media with discussions about Gwen's surprising hairstyle choice, with one writing: “Please Gwen the blonde wig (mop) looks terrible.”

“Gwen fires your stylist…that wig with the bangs is doing you no good whatsoever,” another added.

“Gwen's wig makes me angry,” someone else chimed in.

“Oh Gwen. This wig.'

“Gwen couldn't get a better wig?” another commenter asked.

“You don't even look like Gwen Stefani.” “I miss Gwen Stefani,” another fan wrote

She debuted the sunny new hairstyle on the 26th season of the music talent competition.

Battle Rounds are a crucial stage in The Voice where contestants from each team come together to sing a duet together. The coach then selects the contestant who they believe performed better to advance to the Knockout Rounds.

During the episode, Gwen teamed up with two teenagers – 19-year-old Sloane Simon and 15-year-old Sydney Sterlace.

Both were given the song “Birds of a Feather” by Billie Eilish as a gift, and Gwen realized during rehearsals that that would also be a difficult decision.

Ultimately, she chose Sydney, but the remaining three judges – Snoop Dogg, Reba McEntire and Michael Buble – used their steal against Sloane, who chose Buble.

Snoop put two duos together to fight, with fans getting their first glimpse of his coaching style and being quite impressed.

The hip-hop star opened the show by teaming up Gail Bliss and Christina Eagle to sing Gretchen Wilson's “Redneck Woman,” and later picked Mikayla Ayira and Eliza Pryor to sing Vanessa Carlton's “A Thousand Miles.” .

Many were impressed and took to social media. Some claimed he was the best judge in the show's long history.

While none of Snoop's singers were stolen after elimination, there were two major thefts to kick off the Battle Rounds.

Snoop quickly realized how difficult the Battle Rounds would be after their performance, admitting that it would “break my heart” to choose one over the other.

After channeling his “gangster holy spirit,” he ultimately chose 23-year-old Christina over 61-year-old Gail.

Gail was not stolen by any of the other judges after the performance, so she was sent home.

Buble paired 18-year-old Kiara Vega with 20-year-old Mor Ilderton to sing Iris from Goo Goo Dolls.

Michael realized the song wasn't in any of their “spurs,” and Mor admitted he'd never harmonized before.

The judge ultimately chose Kiara after insisting the decision was “impossible” and even giving Mor his personal phone number… before Stefani swooped in to steal.

Also up for grabs was Team Reba's Kendall Eugene, who chose her over Alison Elena after singing “Bring On the Rain” by Jo Dee Messina and Tim McGraw.

Jan Dan was chosen by Stefani over Jaylen Dunham because Jan Dan had to leave right after because his wife was having their first child that day.

The Voice returns Tuesday, October 22nd at 8:00 pm ET on NBC.
