Late last week, Hayden Panettiere one-upped Entourage star Adrian Grenier by showing off a drastic new cut of her own. The actress - who is pictured here with boxer boyfriend Wladimir Klitschko - debuted the shorter style at an Earth Day event in LA on Thursday.

What do you think of the new look? Do you like the change…or does the Heroes star need someone to come rescue her hair?
