Grammy nominations were announced last night, with Katy Perry making the list in a couple of categories, including Album Of The Year and Best Pop Vocal Album.

No surprise that Lady Gaga is also a nominee in the same two categories as Katy Perry, but who will win?  They are also competing with Justin Bieber, who as you know just won four American Music Awards.

Bieber is also up for Best New Artist, along with Best Pop Vocal Album.  Lady Antebellum is up for Album Of The Year, and John Mayer has returned, earning a nomination for Best Pop Vocal Album.

The one person who will most likely be taking home several awards will be Eminem, who received 10 nominations last night, including Album, Song, and Record Of The Year.  If I had to predict the evening, I will say Justin will win in both of his categories and Eminem will take home at least six awards.  Find out all the winners on February 13th.
