During her amazingly well-dressed promo tour for “The Back-Up Plan”, Jennifer Lopez wore this grey Roland Mouret Aphrodite dress to a photocall in Cologne, Germany.

The diva wore her dress with Emilio Pucci heels, silver and platinum bracelets and hooped earrings.

Hilary Duff wore the same dress last month to the 6th Annual BGC Charity Day in New York City.

She opted for on trend Brian Atwood nude pumps.

Jennifer wins for me as I prefer the shorter length, her heels and the fact that she looks like she put a comb through her hair.
