What movie did Hayden Panettiere plug on the David Letterman show?”
‘Heroes’ hottie Hayden Panettiere wore a barely-there little black dress to ‘The Late Show with David Letterman’ Monday night, where she plugged her upcoming movie ‘I Love You, Beth Cooper.’ The black lacy frock left little to the imagination, but the 19-year-old actress looked cool and confident as she entered the Letterman studios. Panettiere did little to accent the dress and let it speak for itself, completing the look with strappy black heels and her hair pulled up.
