The nominations for the 40th anniversary of the American Music Awards were announced Tuesday.

Rihanna and rapper Nicki Minaj led the pack with four apiece, edging out stiff competition from pop sensations Justin Bieber and One Direction.

Rihanna, 24, was nominated in the category – artist of the year – where she will compete with Bieber, Katy Perry, pop-rockers Maroon 5 and Canadian rapper Drake.

She also won nods for female soul/R&B artist and album for “Talk That Talk,” and will battle Minaj, 29, in the female pop/rock artist category.

Minaj scored two nods for her album “Pink Friday: Roman Reloaded” in both the pop/rock and rap/hip hop categories this year, as well as a nomination for favorite rap artist, alongside Drake and American newcomer Tyga.

Minaj has been making headlines after joining the “American Idol” judging panel, where she was caught feuding on camera with fellow judge Mariah Carey in early audition rounds.

“Boyfriend” singer Bieber, 18, landed three nominations this year, tying with British boy band One Direction, Maroon 5, Drake and R&B star Usher.
