Avril Lavigne, Lil Mama music video girlfriend

Avril Lavigne is a very talented artist but what happens when she teams up with another talented singer Lil Mama (and then drive around in a pink convertible)? Well, a song titled "Girlfriend" is born in which these "teenagers" are all over town, breaking hearts, and making "boys" sleepless. What I love about this music video is that the two artists clearly maintain their artistic integrity but also borrow from each other.
