The stars swarmed the red carpet for pictures at the 2012 American Music Awards (AMAs) tonight (Nov. 18). There were plenty of hits and misses as our favorite pop acts donned their Sunday best. Actually, it felt like more acts were dressing down for one of music's biggest events.

Kesha looked gorgeous in a lacy pink number that she paired it with black nails and geometric black heels, adding edge and fashion-forward energy. Taylor Swift showed off her coltish, legs-for-days in a long-sleeved gold mini with appliques. She was covered up everywhere but her legs, and the eye was drawn right to her gams. The strappy gold heels and bun-with-bangs hairstyle were flawless. It was one of her best red carpet looks all year.

Carly Rae Jepsen was much improved from last week's MTV EMAs debacle. Her sparkly pink mermaid frock was so pretty, even if the 'Call Me Maybe' singer's bangs are still too heavy and distracting. She wore a loose, messy, low bun, which showed off the dress' halter neck. Meanwhile, the top half of Pink's dress looked like a bulletproof chest plate. The bottom was Greek goddess and flowy, a contrast to the hard, constructed and stiff-looking top. She also rocked a suicide roll atop her head.

Meanwhile, the affectionate Jordin Sparks and Jason Derulo were a bit disconnected, clothes wise. They showed plenty of PDA on the carpet, but their outfits? The top and bottom halves of her dress didn't match and look matronly, while Derulo dressed like he's headed to the opening of a nightclub. The neck brace he wore after he injured himself in dance rehearsal earlier this year was bedazzled and fancier than tonight's ensemb.

And would it've killed Sean Kingston to ditch the sneakers for a pair of dress shoes and a suit? Check out these red carpet pictures from the 2012 American Music Awards and let us know who gets your vote for worst and best dressed!
