The Voice judge and Maroon 5 frontman's Overexposed will duke it out with Bieber's Believe for the title of Favorite Album, while the 18 year old's Boyfriend is up against Levine's Payphone in the Favorite Music Video category.
Levine, who scored a whopping six mentions, also scooped nods for Favorite Band, Celebrity Judge, Competition Show, and Song for One More Night, which has just tied Carly Rae Jepsen's Call Me Maybe as America's longest running number one of 2012, and Bieber follows with five nominations for Favorite Male Artist, Pop Artist, and Music Fan Following.
But it appears the category of Breakout Artist will be the most contested - Jepsen, Fun., Gotye, and U.K. boy bands One Direction and The Wanted are all up for the prize.
In the movie categories, People magazine's newly-crowned Sexiest Man Alive Channing Tatum, who this year (12) starred in The Vow, 21 Jump Street, and Magic Mike, picked up four acting nods, and Emma Stone and Jennifer Lawrence tied with three for their respective roles in The Amazing Spider-Man and The Hunger Games.
The winners will be unveiled at the annual awards ceremony, hosted by The Big Bang Theory star Kaley Cuoco, in Los Angeles on 9 January (13).
