This week the American Idol competition got down to its final two singers - Jessica Sanchez and Phillip Phillips. But we're much more interested in the style competition between American Idol judge Jennifer Lopez and actress Rosario Dawson.

For the episode where Joshua Ledet was eliminated J. Lo wore the Salvatore Ferragamo dress from the Spring 2012 runway with Giuseppe Zanotti shoes and a Celine cuff, and showed off her outfit on her Web site where she posts all her AI fashion.

I wonder if J. Lo knew that Rosario Dawson wore the same silk halter-neck gown for the Vanity Fair Oscar Party in February. She paired the dress with dark purple satin double platform Ferrgamo peep toe pumps and simple gold jewelry. Unlike Jennifer who wore her hair down in a natural-looking blow out, Rosario showed off the neckline of the dress with an updo. Both women chose fairly natural beauty looks, so as not to compete or clash with the vibrant color blocking of the gown.

Who do you think wore it better?
