Demi Lovato stepped out at the American Music Awards looking better than ever! The 23-year-old stunned in a chic, classy long dress with an open back and her 20s inspired hair is all sorts of glam! But what we can?t get over is her fabulous winter ready mani! From the shiny black color to the thin, long length we are in love with this look accessorized with some serious ring candy! Our pick for nail of the day definitely goes to the Confident singer!
