Tuesday – and opened up about the "very different, very diverse" songs comprising the album.
"They're a little bit eclectic," Panettiere, 18, said. The actress described the experience of hearing her music on the radio as "scary" and "terrifying," but told the talk show host that she's put a lot of effort into the songs on her debut disc. In fact, the project has been four years in the making.
"[The music] changed so much over the years," she says, "just because my life experiences and who I am as a person is obviously reflected in the music."
When it comes to her own musical tastes, the actress says her listening habits are equally eclectic, name-checking everyone from Luciano Pavarotti to rapper Nas. Panettiere also hopes that spirit permeates her music. Her wish for the disc is simply "[to make] sure that music didn't all sound the same."
With her album on the horizon, Panettiere shows no signs of slowing down. She's already filming the third season of her popular NBC drama. The cast has completed six episodes already.
"Everyone's so excited about it," she says of the upcoming season, which debuts Sept. 22. "It's the same action, the same high-intensity as the first season."
As for juicy plot points, all the actress would say was, "a couple of us actually get to play two different characters [because] for a second we go back and forth between the present and future and our future characters are very different."
