Twinke, twinkle, which lithe star shines brightest in this sequined black dress?
Cameron Diaz strutted her stuff in this Jenny Packham frock back in April on American Idol while Taylor Swift wore her lace mini to the CMT Artists of the Year show in Nashville.
Both kept the accessories simple, but Diaz went with loose locks while Taylor wore her curls pinned back in a bun. So whose style do you like best: the beachy blond actress or the cutie-pie country star?
