The ladies mixed it up on the red carpet at the American Music Awards last night, but most opted to show off their stems. Never one to blend in with the crowd, Beyonce decided to go with the mermaid look that was a favorite back at the Emmys. Rihanna usually looks fabulous on the red carpet, but I think she missed the mark this time around. Luckily she looked much better during her acceptance speech and performance. Overall, most of the ladies managed to look both glamorous and flirty.
