While the actress has said in the past she modeled her "openly nasty" character after the country superstar, Underwood insists she doesn't see any similarities.
"I'm not like that at all," says Underwood in the latest issue of Allure. "It's juicy, but I hope not everybody thinks that everything goes down like that in Nashville, and we're evil. To be honest, I've been fortunate enough to work with other types of music—and we're the least drama-rific people."
To be clear, though, Panettiere was actually inspired by Underwood's stage presence when developing her role as singer Juliette Barnes.
"She's one of those girls that doesn't do the whole dancing-around-choreography thing," she told The Boot last October regarding Underwood. "She can just stand there and be incredibly interesting."
