Hayden Panettiere Has a Ball

Hayden Panettiere is all smiles as she plays ball during some down time on the set of Heroes in downtown Los Angeles on Tuesday (March 10).

Hayden and cast members Cristine Rose (Angela Petrelli) and Greg Grunberg (Matt Parkman) were on location early in the morning at the Los Angeles City Hall — aka the U.S. Capitol — to film scenes from the Heroes season finale.

The L.A. Times blog also spotted a sign for the “Senate Rules Committee.”

The next all-new episode of Heroes, “Cold Snap,” airs Monday, March 23rd
