This week actress Ana de la Reguera brought out the big guns with a Gucci Fall 2011 halter gown that featured a sheer chiffon bottom and flower pedal-eque embellishments when she hit the red carpet of the Cowboys & Aliens world premiere in San Diego.

De ja vu? Yes! Beyoncé was the first to romance onlookers in the same look when she posed for pictures for Harper’s Bazaar magazine on a balcony of a room at the Ritz hotel in Paris.

Both ladies even opted for the same makeup: smoky eyes, pale pink lips and red nails. The only real difference is that Beyoncé wore her hair slicked back in a pony tail and tied her halter top to the back, while Ana’s hair was gathered in a bun and she tied the top of her dress to the side.

Both of them are working it! Which one is your favorite? Vote in our poll.
