The American Music Awards go down tonight in Los Angeles -- and if the past is any indication, there are sure to be some major fashion fiascos.

While last year's red carpet was fairly tame, both Christina Aguilera and Kelly Clarkson hit the stage to perform in outfits that did nothing to flatter their figures.

And who can forget Britney Spears and Justin Timberlake's matching denim ensembles back when they were still an item in 2001?

With performers like Justin Bieber, Carrie Underwood, Aguilera, Ke$ha, Nicki Minaj, Taylor Swift and No Doubt all slated to his the stage, you can definitely expect some wild wardrobe choices this year too.

Check out all the wacky outfits above -- and be sure to come back later today to see all the hot red carpet photos from the 40th Annual American Music Awards!
