My predictions:
She WILL win these:
Top Digital Song - California Gurls
Top Digital Songs artist (I'll be surprised if she doesn't)
She has a shot on these:
Top Hot 100 Song - California Gurls
Top Hot 100 Artist
Top Radio Songs Artist
Top Pop Songs - California Gurls
Top Pop Songs - Firework
Top Pop Artist
No way
Top Female Artist (Lady GaGa will probably win this because of her tour)
Top Pop Songs - Teenage Dream
Top Pop Album - Teenage Dream (Justin Bieber will win

)
