Hayden Panettiere kept it casual as she rolled through the airport in Washington DC yesterday afternoon.

Rocking a grey t-shirt and jeans, she donned a fresh face with some adorable riding boots as she got ready for her departure. Hayden was in town getting honored by DC mayor, Mayor Vincent Gray, who made Friday “Hayden Panettiere Day.”

“It doesn’t get much cooler than that. It’s a huge honor. We’ll continue just chipping away at the problem and trying to fix it.”
