Gwen Stefani has finally unveiled the secret behind her seemingly ageless appearance. The multi-award-winning artist was a massive sensation in the early 2000s, churning out chart-toppers like 'The Sweet Escape', 'Hollaback Girl', and 'Rich Girl'.

Having been active in the music industry since the early 90s, Stefani has since transitioned to being a judge on the popular music TV show, The Voice, and has also launched her own makeup brand, GXVE Beauty.

Despite her decades-long tenure in the limelight, fans are still taken aback by the fact that the 53-year-old artist looks so youthful. Now, Stefani has finally lifted the veil on her beauty secret.

Stefani, accompanied by George Clooney and Julia Roberts, made an appearance on a segment of Carpool Karaoke with James Corden.

During the ride, the host of The Late Late Show was intrigued by the fact that the 'Don't Speak' singer looked incredibly youthful and proceeded to ask her how she manages to maintain her ageless appearance.

"What happens was my life blew up and after that, I kind of started falling in love," she responded.

"Then I wrote a whole record about that."

"That's like what the facelift is, I think."

"It's taken 10 years off you," Corden replied.

In a humorous moment, the comedian quipped that his own wife should tie the knot with a country music star like Blake Shelton if she wanted to maintain a youthful appearance, alluding to Stefani's marriage to the popular country artist.

Stefani's life was turned upside down in 2015 when she found out about her ex-husband, Gavin Rossdale's infidelity.

Soon after filing for divorce, she started dating Blake Shelton, and the couple tied the knot in 2021. Since then, the two have collaborated on several successful songs, including 'Nobody But You' and 'Happy Anywhere,' both of which topped the Billboard country music charts.

In an interview with The Daily Telegraph, Stefani also talked about the attention she receives regarding her appearance.

The 'Just a Girl' artist stated that she is not bothered by the public's fascination with her youthful looks. Nonetheless, she acknowledged that aging can be a sensitive subject for many women.

"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," Stefani said.

"But you tackle it by just trying to be the most beautiful version of yourself inside and out."

"People talking about my aging is a compliment, I guess. I'm kind of obsessed with how I'm aging, too."

Once again, she attributes her youthful appearance to her husband, whom she refers to as her secret anti-aging product.

"Blake is the greatest guy. I look back over the past few years and look at pictures of when I first started kissing Blake, and I look the best I've ever looked in my life in those photos."

"Love must look good on me. I feel like that does show through – it really does," she concluded.
