wow, this was a toughie, lol

to be honest all of them..LOL.

gold lame...lame and LAME!

they all look awful!

it's a tie btwn solange and avril. so fugly

All of them look awful but I had to go with Solange.

I thought Kellie looked fantastic. I can't believe she's grouped with the rest of these mistakes.

Hands down, Kellie Pickler.

Bad enough they looked in the mirror and thought they looked good, but even WORSE that SOMEONE let them walk out of the house like that!

What the eff is up with Rihanna. The rest look okay...i mean they aren't the best but at least they don't look dumpy. Her left breast took one look at this outfit and was like: i am going to break free if it kills me...

what Rihanna is wearing is an expensive sack of potatoes

oh yeah and YAWN, avril lavigne. To think i used to like her. BOOOOOO-RING.

Does Kellie still claim she didn't have a boob job?

they all look horrible! Kellies hair just really bothers me. And the fancy sacks are just gross

that was a very hard vote! they all look trashy!

that was difficult but I couldn't believe Rihanna would wear something so ill-fitting and strange.

Solange Knowles I think for sure!
Look at those shoes with everything else!!! NOOOO

I think Avril looks gorgeous.

it was all about carrie underwood being the worst dressed. it looked like white postits were choking her!

Where is the all of the above option? if i had to pick one it would be Solange

they are all pretty bad, but I voted Rihanna. Avril doesnt looks that bad (compared to the sparkly dollar store skirt, t-shirt and converse she wore on stage) Kelly Pickler...I could care less about her,because shes not a real celebrity. but I agree that she always looks trashy. And Solange...yeah that one is pretty bad too,The shoes are cute and the dress is cute, just not together. but Rihannas dress is sooooo ill fitting that she won my vote. I mean, the dress in itsself is not that bad, its just the way it fits her (or should I say, doesnt fit her) that reall irks me.

I just expected so much more out of rhianna.

all of them

I chose Avril as worst. I give Rihanna props for rocking a Armani Prive dress, which means that it's couture. I kinda like it! That's what couture is all about. Even though it doesn't translate well on the red carpet, it's still a masterpiece.

ALL OF THE ABOVE. Seriously, we need that option.

solange, seriously. Having Beyonce as a sister and a mom who is a designer, you clearly didn't take advantage of that

i say it's at tie. what were they thinking?

What was Rhianna thinking? that top doesn't leave much to the imagination. maybe she was on drugs when she picked this out.

Why does rihanna think that she has to be the center of attention. The dress would have been approriate maybe for another occasion.

They all look bad.. I have to go with Rihanna..

rihanna's boobies are fallin' every which way!

Actually I thought Kelly's dress was kinda cute, the rest awful!

Solange Knowles looks the worst, but Rihanna should totally know better! Armani Prive isn't doing anyone any favors (like Katie Holmes)

I had to vote for Rihanna, mainly because girlfriend knows better.

All of them

i don't know...i voted for Rihanna, but they are all pretty bad.

for me avril took the cake...

What the hell Rihanna? Just no.

(I actually expect that kind of look from the Knowles sisters so Solange gets a free fug pass.)

I don't mind Kellie's dress too much but the rest are dreadful. I had to go with Avril as the worst, but that's because I freakin' loathe her with every fiber of my being.

Solange's outfit looked horrible...but my eyes went immediately Rihanna's travesty, so she got my vote!!!

They're all awful!! I voted Avril just because that gold looks SO hideous on her. She's too pale or something. Just bad.

Solange

this one was a toughy but pink pumps. ick

Oddly Kellie Pickler looks the best out of that bunch - I wouldn't wear any of those.

It was really a toss up between Rihanna and Solange for me.

Solange and Rihanna for me.

And the scary thing is they probably all had MANY people helping them choose the right outfit. I think Solange probably had her mother make/design/choose her outfit which was a bad move. Kellie is the best of these worst but is way over the top. She's trying to be Angelina or something.

Yes, agreed.. We need an all of the above option with category participants like this....

This was such a difficult choice. It's weird, they all look horrible.

They all look equally BAD... I'd say it was a tie between them all !
