Everyone has their own fashion icons who they look up to, and Carrie Underwood spills that her fashion icon is actress Reese Witherspoon. “Reese Witherspoon is one of my favorites, because she seems so normal,” Carrie says in a video on usweekly.com. “I’ve had the pleasure of being in her company, and she’s so sweet. I think we have the same body style. We’re both shorter and can wear the same kinds of things. She’s my fashion icon, 'cause I just think she’s so approachable.”

In the video, Carrie also spills on how she gets her toned legs (lots of squats and lunges, ladies), and how she gets them so shiny. “I drink water like you would not believe," says the singer. "It's about hydration.”

She can also chalk up those killer legs to good genes. “I think genetics plays a little role. God did not bless me with a J-Lo rear end or fabulous arms, but my legs are more muscular than the rest of me. I love to work out and I love to eat and there’s a happy medium to taking care of it.”
