Jennifer's shocking dress

Jennifer Lopez isn't known for bundling up in turtle-necks and gym-pants but her revealing outfit at the Grammy Awards this week still shocked some.

The green $4,000 Versace dress seemed to be missing a few components -- namely a front and a back.

Although Lopez might have worn the dress to be different or stunning or to stand out, someone beat her to it.

Ex-Spice Girl Geri Halliwell wore the same dress last month at a music industry party in Cannes, The English Sun reports. Halliwell also caused a stir when she wore the revealing outfit.

But apparently not everyone had a chance to see Halliwell in the dress. "X-Files" star David Duchovny seemed quite impressed when he joined Lopez on stage to present a Grammy award.

"This is the first time in six years that I'm sure no one is looking at me," he said.
