There were some hot looks at the 2013 American Music Awards last night ... but these weren't them.
Keep reading to see which stars we picked as the Worst Dressed from the AMAs. Plus, click here for the flipside -- and see who looked the best!
5.) Aubrey O'Day
Look, we're happy that Danity Kane is coming back (let's be real, "Damaged" was an awesome song!), but this isn't the best way to start a comeback.
Aubrey looked like her girls were going to pop out of her ridiculously low-cut red dress on the red carpet at any moment. And while a slit is always welcome in a dress, there's no need for one on both sides!
4.) Kelly Osbourne
Kelly Osbourne has been such the fashionista lately, seeing her like this really hurts. The "Fashion Police" star may have to turn the tables on herself after wearing this unflattering frock to Sunday's event.
Her svelte figure gets lost in all that pattern on the bodice and the embellishments on the tulle remind us of a figure skater's costume. On the plus side, we love the hair 'do!
3.) Jennifer Hudson
The color on this dress is fierce on J-Hud, but the rest of it is a mess. It looks like she took a pair of scissors to the bottom and stopped cutting halfway through.
What the heck is going on here?!
2.) Emma Roberts
This look was a real horror on the "American Horror Story" star.
Emma has a great figure and this does absolutely nothing for it, giving her a weird chest and midsection ... and the material just looks cheap. Her hair looks cute, but that's about it.
1.) Lil Mama
O.K., so the fit on the bodice is actually quite nice -- but the fact that Lil Mama matched the rest of her look with her hair is a big turnoff.
We just reallllly don't like that green color on her head or her outfit in general. It all adds up to a decidedly alien look, don't you think?
Bonus Entry: Miley Cyrus!
While the singer didn't wear this outfit on the red carpet, Miley sported another of her vulgar leotards during her "Wrecking Ball" performance. Ew.
