New Single From Hayden Panettiere: 'Your New Girlfriend'

The Hayden Panettiere Countdown is over!

Hayden's new single, "Your New Girlfriend," has hit the Internet.

(Wait, what did you think I meant, you sick bastards?)

Panettiere is best known for her acting work in "Heroes" and Remember The Titans. She has already contributed songs to the soundtracks of several movies, including Cinderella III and Bring It On: All or Nothing. This fall, she'll attempt a full-scale pop career with the release of her album Fallen Love (different sources have the album coming out anywhere between September and December of '07).

Here is the single.
