Kelly Clarkson: Pregnant, Fat or Fashion-Impaired?

If Kelly Clarkson is tired of pregnancy rumors, she might want to avoid clothing choices like she's donned recently. The singer looked considerably heavier performing at the KIIS-FM Wango Tango in California this weekend.

Contrast how the original American Idol looks compared to just two months ago, when promoting her new album on the current season of the hit show.

Maybe she was channeling her inner Jessica Simpson and just picked a really unfortunate outfit. Sorry, that's a huge insult to Kelly Clarkson to even be mentioned in the same sentence as that sorry excuse for a singer. Our bad!

Anyway, is she with child? Overweight? In need of a mirror?
