Kellie Pickler became America's sweetheart when she showcased her powerful pipes and bubbly personality on 'American Idol' back in 2005. Kellie, now 23, has grown into a young woman in front of her fans, which she says has been a bit awkward.

"It's hard to make that transition from a teenager to an adult," Kellie tells The Boot. "Growing up in front of everyone is tough, because they don't want you to grow up. People see me on 'Idol,' and they want me to stay the same and expect me to be the exact way that I was on the show. That's just impossible for anyone to stay the same their whole life. When you look at anyone who is 25, 30 or even 40, they're not the same person they were when they were 18 years old ... I'd hope not, anyways! Hopefully they've matured and grown up and been through a lot of life experiences and have more wisdom and knowledge."

Kellie is currently in the midst of the 2010 Fearless tour with Taylor Swift and Gloriana. The North Carolina native's latest single of her self-titled sophomore album is 'Makin' Me Fall in Love Again.'
