Lil' Mama & Avril Lavigne!
For future reference, I just want it to be known that I always liked Lil' Mama. She lyrically smashes most of the female MCs in the industry today, and if you don't believe me it's probably because you haven't heard the girl spit. This video is decent - upbeat, fun, and the dancing is satisfying. No beef here.
Oh, and Avril is cute, too.
