Jansen Panettiere at the premiere of Wall-E.

Jansen Panettiere was one of many Disney stars that attended the premiere of the new movie Wall-E, at the Greek Theatre at the end of last month. Wall-E is a movie about a robot who cleans up the earth, after it’s no longer inhabited. I haven’t seen the film yet, but I’ve heard it’s pretty darn good.

Alongside Jansen Panettiere, younger brother to Hayden, was a million trillion other people. Click here to view the list of celebrity guests in attendance.

Jansen is thirteen years old, and actually starred alongside his sister Hayden Panettiere in the Disney Channel Original Movie, Tiger Cruise.

Here’s a video clip of the song Hayden Panettiere performed for the movie, which includes footage from the movie itself, as well as footage of Hayden in action, inside the studio.
