Gwen Stefani is one of the most glamorous women in the world, but in a new interview, she admits that she didn't feel that sexy until she met her boyfriend, Blake Shelton.

Stefani sat down with her longtime friend, supermodel Heidi Klum, for an interview with InStyle, and when Klum asked her to describe her current sense of style, she replied, "More feminine than ever before. It’s probably because I’m super in love and have a really manly man [Blake Shelton]. I enjoy letting that part of me come out now because when I was in No Doubt, I never thought of myself as sexy. Even in my 30s, I was a tomboy. I hardly ever carried a purse."

She names the red floral dress that she wore the first time she and Shelton appeared in public together as her favorite outfit of all time, saying, "The red Yanina Couture dress I had on when Blake and I stepped out for the first time. That was a magical night, and I loved the flowers."

Shelton and Stefani got together in 2015, after his divorce from Miranda Lambert and her divorce from Gavin Rossdale. They have become one of the most talked about and photographed couples in celebrity culture, but the pair still find plenty of time to be alone and casual.

Most recently, Stefani spent time with Shelton for his birthday at his tropical-themed lakefront estate in Tishomingo, Okla., and she shared some fun pictures with fans online.
