Hayden Panettiere Stomachs Piercing Pain

Hayden Panettiere lifted her shirt for a camera last night -- but the only thing going wild was her navel.


The "Heroes" star went to Prix Body Adornment in West Hollywood on Monday to re-pierce her taut stomach ... and was more than willing to show off her '90s belly bling on the way out.

Abs-olutely fabulous.
