Hayden Panettiere — Childbirth Ruined Parts of Me

Hayden Panettiere can’t getting away from the laws of physics — birthing Wladimir Klitschko‘s baby did some stable hurt to her bod.

Hayden copped to the ordeal of bringing Kaya into this world with People … saying, “I’m limping around. I’m still trying to figure out what [pregnancy] has done to my body, how it’s changed it.”

As for recovery … she added, “I know some things will never be the same again.”

Sounds about right — Kaya was 7 lbs., 14 oz. and damn near 2 feet tall. Hayden’s only 5 feet tall. Like we said … physics.
