The tight pair of buns below - covered by the shortest of short shorts - belongs to everyone's favorite TV cheerleader, Heroes' Hayden Panettiere. Yowza.

We have no comment you haven't heard some version of before, or that doesn't make us incredibly dirty, so we'll just shut up and let you enjoy the pic ...

Hayden, who was recently presented a gold ring - a belated birthday present from "friend" and Heroes co-star Milo Ventimiglia - might want to pawn it and buy some jeans. Otherwise, not a lot of work is gonna get done around here.
