Lady Antebellum, whose self-titled debut album has been out less than a year, is enjoying a meteoric rise to stardom. With a No. 1 album, two Top 20 singles, and now two coveted Grammy nominations (for Best New Artist and Best Country Performance by a Duo or Group), this band that has been together less than three years are certainly feeling overwhelmed.

"I don't think I've really comprehended it, because I still feel like I'm this dorky girl who likes to write songs and wear fancy clothes," Lady A's Hillary Scott tells The Boot. "It's definitely been a year of such amazing things. And now that we're here, we really have to prove ourselves, because so many people are going, 'Who are these people?'"

Joining two of country's most successful tours -- Kenny Chesney in the states and Keith Urban in Canada -- it's highly unlikely Lady A will stay a little-known act for long. Still, in spite of their success, Scott says they're not getting cocky ... or lazy.

"We don't want to be a blip on the map," she says. "We want to have staying power and build a career and not just be a flash in the pan. So now is when we really buckle down, bust our butts and prove ourselves."
