Hayden Panettiere Shows Her Sexy Side in New Carl's Jr. Commerical

Hayden Panettiere is showing off her post-baby body in Carl's Jr.'s hot new commercial.

The actress, 26, wears Daisy Dukes and an unbuttoned chambray top in a sexy ad for the fast food chain's new Midnight Moonshine Burger.

"Frankly, I like to eat a burger," Panettiere tells PEOPLE. "I'm Italian, so I'm not very good at curbing myself. I think that we should allow ourselves that. I think [otherwise] then we'll all end up hangry, and nobody wants to be hangry!"

For the Nashville star, showing off her sultry, confident side was a big step after overcoming her battle with postpartum depression.
