The R&B singer, 21, is up for five Grammys Feb. 8 for her hit debut, Fearless.
ON THE GRAMMYS It's like a dream right now. Hopefully I can [perform]. I would love for Stevie Wonder to play for me, but that's just my high hopes!
ON BEING FULL-FIGURED I'm very confident in who I am. I'm happy to be a role model for other women who can look at me and say, "She isn't starving herself." But I'm starting to work out more now.
ON MENTOR MISSY ELLIOTT She's taught me a lot, makes me work harder. If I ever need anything, I just call her up.
ON HER HIT "BUST YOUR WINDOWS" It is a true story [about vandalizing the car of a cheating boyfriend]. I'm not very proud of doing it, but it has helped my career!
