Do you like Hayden Panettiere's new 'do (and her new 'Heroes' competition)?

We're psyched (and relieved) to see a new hairstyle on "Heroes" cheeleader Hayden Panettiere, seen here with costar Greg Grunberg at the Ford Flex Rally party.

Frankly, that cheerleader shoulder-length layered 'do was looking tired.

What do you think of Hayden Panettiere's sleek new center-parted bob? We will have to wait and see if her hair has superpowers and will grow back on the show instanteously, the way her broken limbs and injuries heal.

See more photos after the jump and check out Brea Grant (you may know her as Jean on "Friday Night Lights"), Hayden's new blond competition on the new season of "Heroes."

Word is Brea's superpower is speed. The girl is fast. Real fast. Even when Masi Oka stops time fast!

Brea told the Associated Press, "I'm stealing a secret that's been kept in Hiro's family for a long time that he's just now found. He stops time right as I grab it, but in that second it took him to grab it, I almost make it out of the office."

According to Masi, "Her character is supposed to be Hiro's Joker. Batman has the Joker. Hiro has Daphne. This is the season where Hiro finally finds his arch-nemesis, and it happens to be this Speedster. I kind of equate it more to Wile E. Coyote and the Road Runner, except Daphne says more than 'meep meep.'"

Better watch your back, Hayden. This girl may run circles around you in less time than it takes to regrow your hair.
