Who’s that girl?! Hayden Panettiere returned to social media this week with a brand new look after a 10-month-long silence on Twitter. Showing off her pouffed-pixie coif, she captioned the cute shot, “Channeling my inner #Kirby #Scream4 Thanks to my boys @anthonyleonard ,” a reference to the short ‘do she wore in “Scream 4.” We like!
