While looking gorgeous on the red carpet at the 2014 Emmys, Hayden Panettiere accidentally revealed the sex of her baby! She was chatting with Giuliana Rancic when she announced the news: it's a girl!

Before the awards show, Panettiere simply glowed while she showed off her baby bump in a sparkling Lorena Sarbugown floor-length gown with plunging neckline. "I can't wait for her to come out," the 'Nashville' star let slip to Rancic. Rancic was taken aback, but obviously excited! She exclaimed, "It's a girl?!"

“Yes, it’s a little girl," the 25-year-old revealed. "I want to go shopping, I want to paint the room … I’m working with my amazing interior decorator, Ben Vandiver, who did my house in Nashville. He’s trying to do something that she can grow up in and you don’t have to change everything."

This will be Panettiere's first child with fiancé Wladimir Klitschko, and she admits the two haven't picked out a name just yet. They're having to go to even greater lengths to make sure they pick something that is both American and Ukranian. “We’re still working on it, but we have some options," Panettiere shared.

Although she made pregnancy look easy (and beautiful) while at the Emmys, the actress reveals she wasn't exactly comfortable.

“I love [Lorena] and she did such a fabulous job -- the only thing that’s difficult, honestly, is making sure everything is tucked in away and in there, and then the shoes. Walking around all night in the heels -- my feet get sore when I’m wearing no shoes," she said. "My size 5 feet have never felt this amount of weight on top of them!”

'Nashville' returns for a new season on Sept. 24 at 10 PM ET on ABC. Panettiere's character on the show, Juliette Barnes, will be pregnant in Season 3.
