Hayden Panettiere Flexes For Ford

Hayden Panettiere shows off her short new do at the Flex Rally 2008 charity event at Edison Downtown on Saturday in Los Angeles.

Earlier in the day, the 18-year-old Heroes hottie was seen sporting a pony-tailed brunette wig while shooting a gun. Hayden was also seen getting hot and heavy with costar Milo Ventimiglia.

The Ford Flex Rally was a charity event launching Ford’s new crossover SUV. It’s also a scavenger hunt in which 10 celebrity teams drive the 2009 Ford Flex around looking for clues. Ford partnered with charity Band From TV for ultimate adventure in the new 2009 Ford Flex.

The event, starting Saturday, was hosted by “Band From TV” formed by Heroes star Greg Grunberg and peopled by the likes of Hugh Laurie (House), Teri Hatcher (Desperate Housewives) and Jesse Spencer (House).
