AMAs 2012 best dressed: Carrie Underwood, Nicki Minaj and Justin Bieber's mom among the highlights

The red carpet for "The 40th Anniversary American Music Awards" was sadly lacking in major wow moments, but a few looks stood out among the crowd.

Amy Heidemann joined fiance and Karmin bandmate, Nick Louis Noonan to introduce No Doubt's performance. But not before turning heads with one of the only daring looks of the night. Amy's Falguni and Shane Peacock cutout dress was perfectly complemented with a spark of Nars velvet matte lipstick pencil in Red Square.

Nicki Minaj surprised us by toning it down and classing it up with her lime green Monique Lhuillier gown. Surprisingly lacking in garishness from head-to-toe, this is the best Minaj has looked on a red carpet in a while.

Carrie Underwood looked lovely in lace, pulling off the glamazon look in a purple beaded floor-length. Too bad her hair doesn't live up to the glamour of the dress -- we're not big fans of the hat head look.

Jenny McCarthy's harsh styling was a bit reminiscent of Brigitte Nielsen, but her black strapless and gold sequin dress was 80's fabulous. 

Justin Bieber's mom, Pattie Malette, was called in at the last minute to fill Selena Gomez' shoes, and she did a pretty bang up job for not being a celebrity with a stylist.
