Nicki Minaj will be slugging it out again big time—and it won't be against Mariah Carey!

Big Barbz and Rihannadominated all nominees for this year's American Music Awards with four nods apiece.

The noms were announced Tuesday by Christina Aguilera, who will also be performing at the show on Nov. 18. (Two for one!)

Following closely with three nods each are Justin Bieber, Drake, Maroon 5, Usher and One Direction.

This year, there's no shortage of drama among the artists who'll be battling for prizes.

Rihanna will be competing with not one but two exes: Drake, for Artist of the Year; and Chris Brown, for Favorite Soul/R&B Album.

In the heartthrob department, Biebs goes up against boy band du jour One Direction for Favorite Pop/Rock Album.

Even kiss-happy, scandal-plagued Jason Aldean scored himself some love with a nod for Favorite Male Country Artist.

For the sixth year, winners will be determined by online voting, which kicks off today. This year's awards, which will celebrate the show's 40th anniversary, will be handed out on at Los Angeles' Nokia Theatre and air live on ABC.
