Eminem & Bieber outscore Lady Gaga in AMA nods

But Lady Gaga earned just two nods despite dominating the music industry for the past year. Eminem, back on top of music charts with a best-selling album "Recovery", and Lady Antebellum, earned five nominations each, closely followed by teen idol Justin Bieber, 16, with four.

Bieber and Eminem will compete with Lady Gaga, "California Gurls" pop singer Katy Perry, and newcomer Ke$ha for the artist of the year award -- the biggest prize of the night at a televised live ceremony in Los Angeles on November 21.
