The Texas-born Lambert says this look reflects what she's like at home, where she doesn't wear much makeup outside of "some tinted moisturizer and sunscreen and mascara. And lip gloss! It's kind of an addiction."

Lambert keeps a glam squad on call for red carpet events, but does her own hair and makeup on tour. "I have a product bag the size of Texas-just makeup and hair stuff and curling irons," Lambert said.
