Lil' Mama

The Album: The Voice of the Young People, due this fall
LISTEN: Click here for "Lip Gloss."
The 411: Her first single is an ode to lip gloss. "I like pink, hot pink and light pink," says Lil' Mama, 17, of her favorite colors. But the New York rapper's debut isn't only skin deep. "I'm a leader of the youth," she says, and as a lyricist, she doesn't use bad words to set an example for her siblings – all seven of them.
Dishing on Avril: "When I met her [to work on the "Girlfriend" remix] she was calm, cool and collected and I'm hyperactive. It was a perfect combination."
