Gwen Stefani may be 51 years-old, but she looks better than ever, and she is well aware of that!

In a new interview with The Daily Telegraph’s Stellar, Stefani opened up about what it is like to age in the entertainment industry, and to reveal her secret for looking so young.

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

Stefani added that she’s feeling and looking her best thanks to her fiancé, Blake Shelton, and being in love.

“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,” she said. “Love must look good on me. I feel like that does show through — it really does!”

Stefani and Shelton have been dating since 2015, when they met on the set of “The Voice,” and they became engaged back in October. Back in December, a source told Entertainment Tonight about Stefani and Shelton’s plans to spend their first Christmas together as an engaged couple.

“Gwen and Blake have spent a great deal of time reflecting on what they have to be thankful for. With their recent engagement and the holidays coming up, they truly couldn’t be happier,” the source said. “Gwen and Blake are excited about their first Christmas engaged and want nothing more than to just enjoy being together as a family. Right now, they are focusing on staying safe and isolating.”

An insider recently told Closer Weekly that Stefani’s sons Kingston, Zuma and Apollo “can’t wait” for her to marry Shelton, adding that “he already had a close bond with the boys.” Shelton, 44, has reportedly spent a lot of time with his 51 year-old fiancee’s sons over the past five years.

“Blake treats Gwen’s kids like they’re his own,” the insider explained “He adores them, and they love spending time with him. Blake’s relationship with the kids won’t change much once he officially becomes a stepdad.”
