With all the reports of on-set feuding between Mariah Carey and NIcki Minaj, we almost forgot what "American Idol" was all about: The talent.

The show returns tonight with Mimi, Nicki and Keith Urban joining Randy Jackson on the judging panel ... and we've got a sneak peek at some of the best and worst auditions from the big two-hour premiere.

Check out the video below to see which tryouts left the entire panel with their jaws on the floor ... and not for a good reason.

There's a Justin Bieber wannabe, a crazy dancer, wild costumes and a version of "We Will Rock You" tailor-made for the judges.

Of course, it's can't all be bad!!

We also got our hands on some of the good auditions you can expect to see more of tonight -- including a hottie the girls will be swooning over and a female singer who clearly impresses Mariah.

Check them out below:

Are you looking forward to the new season of the show, new judges and all?
