Ooh, we love a riddle . . . And this is a riddle of the prettiest kind! It's a luxe video, shot by a famed Hollywood director, starring a famous Hollywood actress. The catch is, we don't get to find out who the actress is until Tuesday, December 4, when the full video is released. So far, we've got four videos offering us visual clues — we know the actress has blonde hair, is slim, and she's wearing a ruby-red embellished dress. Watch the videos above and below, then cast your vote for who you think it is — and be sure to check in here on Tuesday for the full video!
