The Nashville actress confirmed her pregnancy last week as she took part in the ALS Ice Bucket Challenge and she looked absolutely stunning as she showed off her baby bump at last night's 66th Primetime Emmy Awards.
Joining fellow TV stars at the Nokia Theatre in Los Angeles for the annual event, Hayden took part in a little pre-awards interview with Giuliana on E!'s Live from the Red Carpet show when she revealed her secret.
"I'm thrilled for her to come out," Hayden blurted out when Giuliana questioned about her exciting news.
Realising, she had totally let the cat out of the bag, Hayden then exclaimed: "I just said that, didn't I?"
You did indeed, Hayden!
She also talked about how she and her fiancé, Ukrainian boxer Wladimir Klitschko are having tough times coming up with a fabulous name that works in both American and Ukrainian!
And that her love of chicken noodle soup is just getting more and more accentuated throughout her pregnancy.
Congrats to you guys and, by the way how fabulous did Hayden also look on the red carpet?
Dressed in a Lorena Sarbu sequinned dress she managed to pull off sexy without showing off too much flesh.
Nice work Hayden!
