2013 Grammys Red Carpet Fashion – Jennifer Lopez and Her Thighs Wore Black Anthony Vaccarello

Whoa. At first, you would've have thought that diva and glam goddess Jennifer Lopez didn't heed the Grammys warning about the dress code -- which advised against side boobs, butt cracks and nip slips -- because the diva showed some serious leg.

But hey, as she pointed out, the rules said nothing about leg.

The singer/actress/dancer/fashion designer/perfumer wore a black Anthony Vaccarello gown that was asymmetrical, baring one thigh and one shoulder. The front slit was cut up-to-here, leaving little, if anything, to the imagination. Leave it to J. Lo to make a thigh the sexiest thing we've seen all night -- and to channel Angelina Jolie at the same time.
