Spending the day on the set of her hit NBC series, Hayden Panettiere was spotted filming a scene for the upcoming season of "Heroes" in Los Angeles on Wednesday (September 2).

Wearing a pink and white cheerleading outfit, the 20-year-old cutie also spent time chatting it up with the local police on set - who seemed to be quite taken with the young actress.

As for the new season of "Heroes," Hayden recently told press: "My character's in college and I'm working with a great girl named Madeline Zima, who plays Claire's new friend/roommate, Gretchen."

Talking about her relationship with her fellow co-stars, Hayden reveals, "I do [get along with older people]. With younger people, I sometimes struggle to fit in. I have plenty of confidantes and friends in the cast."

You can catch Miss Panettiere and her co-stars in action when Season 4 kicks off with a two-hour special on Monday, September 21 at 8/7C on NBC.
