The 53rd annual Grammy Awards, the biggest night in music, take place live Sunday night. Eminem leads the field with 10 nominations, with his comeback album "Recovery" up for Album of the Year and his song with Rihanna, "Love The Way You Lie," up for both Record of the Year and Song of the Year.
Phenom 16-year old Justin Bieber is up for Best New Artist, taking on Drake, while he faces off against the big league likes of Lady Gaga and Katy Perry for Best Pop Vocal Album.
