Gwen Stefani is known for her ultra-glam looks, but the singer made a case for going completely natural in a stunning makeup-free selfie shared to Instagram. With tousled hair and remarkably clear skin, the "Voice" fan favorite looked decades younger than she actually is, and followers took note in the comments. "More beautiful au natural for real," wrote one, while another gushed, "love the no make up look luv," and a third quipped simply, "Much better without makeup!" 

Although we'd all love to know what her secret is, Stefani reckons it's just being happy. "I look back ... 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," she told the Daily Telegraph. 

Stefani takes it as a compliment that people think she's aging beautifully, though she admitted to feeling pressure because of it, too. As for her skincare routine, it's pretty low-key. "I don't have a huge routine, but I wash my face with some cleanser that takes makeup off. I just recently started using these pads from a dermatologist that takes more makeup off," Stefani revealed to InStyle. The former No Doubt star also admitted, "I think about [when I was on tour] on a bus, trying to wash my face in that little sink. That's what I did forever!" Clearly, it didn't do much damage at all to her flawless complexion.
