Wladimir Klitschko calls Hayden Panettiere 'hero' for delivering '7lbs baby'

Wladimir Klitschko has said that his baby momma Hayden Panettiere is tougher than any boxer.

The 38-year-old boxer said that Panettiere, who managed to give birth to his huge baby, who weighed 7lbs. 14oz., or any other woman for that matter, was a "hero" for bearing the birthing pain, TMZ.com reported.

Considering that actress, 25, stands at only 5 feet, it was indeed a task to give birth to her daughter Kaya 2 months ago, who was nearly 2 feet tall.
