Congrats Hayden!
It's official!
Taking a page out of Zoe Saldana's playbook, Nashville star Hayden Panettiere, 24, finally confirmed all of the pregnancy reports while participating in the ALS Ice Bucket Challenge Wednesday.
Nominating country singer Kacey Musgraves, fiancé Wladimir Klitschko and "her unborn child" to take the challenge next, Panettiere was doused with ice cold water with a little help from Dancing with the Stars pro Derek Hough.

"Couldn't figure out how to post it on @haydenpanettier twitter so I'm posting it for her . #als #icebucketchallenge (Hayden shortly went into labor after this ) Jus kiddin," Hough posted on Instagram.
Though unlike Saldana -- who cited her obvious baby bump as the reason she couldn't participate in the challenge herself and nominated her husband Marco Perego instead -- Panettiere was actually game to get doused with freezing cold water.
"Yup, that's cold," she smiled.
The ALS Ice Bucket Challenge has turned into a celebrity phenomenon, and has raised over $13 million in donations since July 29.
