Looking lovely in a little black dress, the "I Love You Beth Cooper" babe posed for pictures before heading inside to tape the "Late Show with David Letterman".
Meanwhile, Miss Panettiere recently voiced her hopes to be a respected actress, saying, "I love acting. It's something I respect. It's something that makes me want to be respected for what I do. I'm working toward being a respected actress. Meryl Streep is it for me."
The "Heroes" actress adds, "Just because I'm in the spotlight doesn't mean I'm God's gift to the world. I do have cameras in my face all of the time. Fame leaves you no room to mess up even slightly, and things get turned around on you. That's why I feel you really do have to live your life conscious that people are watching. There are certain things you just can't do."
Enjoy the pictures of Hayden Panettiere out for the Late Show (July 6).
