‘Nashville’ Star Hayden Panettiere Shows Fit Form As She Films New Carl’s Jr Ad

Hayden Panettiere has all about lost her post-baby weight as the "Nashville" star walked around the set of her new Carl's Jr ad in Los Angeles, while looking all sexy in an all-denim outfit.

"The 5ft actress flashed her toned and tanned legs all the way down to her cute brown ankle boots," reported Daily Mail.

"On top she wore a navy shirt, although it wasn't very buttoned up; as is the nature of the ads, she kept tons of cleavage on display," it added.

Hayden Panettiere joins a long list of celebrities who appear in new Carl's Jr. commercials, such as Paris Hilton, Kim Kardashian, Padma Lakshmi and Jenny McCarthy, along with models Kate Upton, Heidi Klum and Charlotte McKinney.

"Hayden, who's engaged to former heavyweight champ Wladimir Klitschko, grinned to herself as she followed her make-up artist across the lot," the article added. "Knowing that she would soon join the immortal ranks of sexy stars to hawk the charbroiled burger."

It's good that Hayden Panettiere seems happy while filming the new Carl's Jr. ad, especially after her revelation that she's seeking treatment for post-partum depression last year.

The "Nashville" actress has a baby daughter, named Kaya, with former heavyweight boxing champ, Wladimir Klitschko.

Speaking to E! News, Hayden Panettiere said that just going public about her post-partum depression made her life better.

"I do feel and hope it's made other people's lives better and more of an understanding because postpartum depression was not something that I ever understood," she said. "You could never understand it unless you have a personal involvement with it."

"I didn't realize how much of a stigma it had about it," the "Nashville" star added.

It's not clear yet when the new Carl's Jr ad featuring "Nashville" star Hayden Panettiere will come out, but going by her outfit, it promises to be very sexy as well.
