No Doubt singer Gwen Stefani has left fans baffled and has been branded unrecognisable following her appearance on the American chat show Late Night With Seth Meyers

Music legend Gwen Stefani has left fans confused after her appearance on the American chat show Late Night With Seth Meyers, with some viewers branding her “unrecognisable”.

The Don’t Speak songstress, 52, sat down for a chat with the talk show host as she flaunted her signature long blonde hair and surprisingly youthful looks.

Gwen wore a black black cut-out maxi-dress which she paired with purple fishnet sleeves. She opted for heavy eye makeup and a nude coloured lipstick.

The musician talked to 48-year-old Seth about her varied career, though some fans seemed to be distracted by her appearance as she hadn’t seemed to age.

Commenting on a YouTube clip of the interview, one person said: “I’m a lifelong fan of Gwen’s and I didn’t recognise her. I’m so confused.”

Another fan wrote: “Would never have known this was Gwen Stefani without the title!”

A third person commented: “I thought it was Jocelyn Wildenstein at first. Gwen is unrecognizable,” with someone else adding: “I’m old enough to remember her with pink hair and braces. Can’t believe how different she looks now.”

“Could have given me 100 guesses who that was from the thumbnail alone and I’d have never guessed Gwen Stefani,” penned another fan.

Don’t MissIt’s not the first time fans have commented on Gwen’s age-defying looks.

Back in May, she shared several selfies of herself to Instagram in the back of a car, as she appeared to be wrinkle-free.

One person said: “How the heck do you look 16???? So stunning,” with another commenting: “What fountain of youth do you use?”

Gwen is known for looking younger than her years, something which the singer acknowledged when speaking to the Daily Telegraph.

“People talking about my aging is a compliment, I guess… I’m kind of obsessed with how I’m aging, too,” she said.

Gwen added: “It’s really hard for everyone to age and have to face life. Especially for females and people who have been in the spotlight.

“It can be daunting, but you tackle it by just trying to be the most beautiful version of yourself inside and out.”

Speaking to Vogue about her on-going career and ageing, she said: “This is the thing about age—there are days when you think you’re expired. Then there are other days where you’re like, I’m not dead. Why stop now?”
