Hayden Panettiere Reveals She's Having A Girl At The Emmys

This is the first child for the 'Nashville' star.

As if she didn't look gorgeous enough already, flaunting her baby bump on the Emmys red carpet, Hayden Panettiere revealed on August 25 that she was expecting a... Drum roll:

Baby Girl! The former "Heroes" and current "Nashville" star first revealed she was pregnant on May 28, her first child with fiancee Wladimir Klitschko.

And now, after speaking with E! Online, we know the sex of the baby.

"I can't wait for her to come out, this little one," Panettiere said, accidentally revealing the gender.

Congratulations to Panettiere and Klitschko, who are still choosing a name somewhere between American (Panettiere's nationality) and Ukranian (Klitschko's nationality).
