Miranda Lambert always sizzles on the red carpet – Exhibit A: her stunning (and plunging!) look at the Academy of Country Music Awards – but away from the spotlight, and scrubbed free of all makeup, she still shines just as bright.
"I don't wear a lot of makeup at home," says the country singer, who agreed to pose for PEOPLE wearing no makeup at all for our annual World's Most Beautiful issue. "When I'm just off and hanging out I just put on some tinted moisturizer and sunscreen and mascara. And lip gloss! It's kind of an addiction."
In fact, her glam squad is only on hand for red carpet events and video shoots. "On tour I do my own hair and makeup," Lambert, 31, says. "That's my time to focus and calm down, listen to music and warm up a little bit. I have a product bag the size of Texas – just makeup and hair stuff and curling irons."
So what does her husband, fellow country star Blake Shelton, think of all those powders and potions?
"He's one of those dudes who's like, 'You look prettier without it,'" she says. "I think, 'Stop! Really? This took me three hours!' But he doesn't care. He sees me the same, whether I have a whole glam squad or I'm just hanging out at home."
