Jennifer Lopez vs. Victoria Beckham — Fashion Faceoff

Kim Kardashian had better watch her back! Jennifer Lopez is now overtaking the reality star as the celebrity most likely to wear the same ensemble as another. In recent months, the singer/actress has stepped out in the same designs as Emma Stone, Julianne Hough, Brooklyn Decker, and Mel B, with a record of two wins and two losses. But now, J.Lo takes on the most stylish member of all of the Spice Girls — the posh Victoria Beckham! The two both rocked a fun, curve-hugging tangerine dress from Beckham's own Spring/Summer 2012 collection. Uh-oh. Lopez's chances don't look good here. It's time to determine ... who wore it best?

Lopez, 43, actually debuted the dress, wearing it on "American Idol" in April. Sigh. With the news that Lopez won't be returning to the reality competition, primetime just got a lot less fashionable! In what would turn out to be one of her last looks for the show, Lopez paired the garment with hoop earrings, a cuff bracelet, and Lanvin ankle-strap sandals.

Beckham, 38, wore the frock for a July 9 event celebrating "Idol" creator Simon Fuller's birthday in London. Sporting a ponytail, she accessorized with nude Giuseppe Zanotti heels and a white handbag.

Pop star-turned-designer Beckham obviously has the advantage here. After all, she designed the dress! She's undoubtedly thought about it and how to style it more than anyone, and it shows, as she looks simple and chic. Lopez, on the other hand, didn't quite get the memo. The "Selena" star's hair falls over the frock's strap detailing, and her jewelry takes away from everything. For me, this is one style showdown that Lopez loses. Do you agree?
