Hayden Panettiere stepped out last night in Washington DC for the Green Ball at the Melon Auditorium.

The Heroes starlet was with her mother, Lesley, as she mingled with other notable celebs including Wyclef Jean and Jackson Browne.
The attire is Green (or Black) Tie. Hayden is an avid supporter of Barack Obama and I’m sure she’ll continue to be an environmental advocate during the course of his term in office.
