Jennifer Lopez vs. Mel B — Fashion Faceoff

Two pop stars as famous for their fashions as they are for their music, Jennifer Lopez and Melanie Brown (aka The Spice Girls' Mel B), recently dared to rock the same frock! Both ladies chose a charcoal, snakeskin-textured sheath from Lanvin's spring line. Now J.Lo's had the most musical success lately, but do you think she can pull off a win in the fashion department? It's up to us to decide just who wore it best?!

Lopez, 42, donned the dress (and a top knot) first on "American Idol" in April. The singer/actress/style icon accessorized with Celine jewelry and spiked Christian Louboutin heels. Too bad it'll end up being one of her last "Idol" looks — Lopez announced this month that she won't be returning to the reality competition show. But while fans won't get their weekly dose of "Jenny From the Block" in the fall, perhaps they can catch her concert tour with Enrique Iglesias (and boyfriend/concert choregrapher Casper Smart) this summer.
