With new wardrobe guidelines in place at the 2013 Grammy Awards, the stars really pushed the envelope with one of the night's biggest trends: cutouts.
Keys flashed some skin and mega curves in a hot Alaïa gown accessorized with sparkling black and diamond jewels.
Rowland also looked stunning in a Georges Chakra number that had perfectly-placed sheer cutouts, while Osbourne played it safe (by Grammys standards, at least) in a Paule Ka gown with geometric holes only on the side.
Mama-to-be Amber Rose kept her baby bump covered up, but front and center, in a long-sleeve Donna Karan dress that showed a bit of décolletage.
Others wearing dresses with missing pieces on tonight's carpet include Natasha Bedingfield in a gorgeous red, belted dress by Emerson, model Karlie Kloss in a classy, knee-length Michael Kors design and Jenna Jameson with a side of mohawk in a (not so) shocking Michael Costello gold gown.
What do you think of the red carpet cutout reoccurrence? Too much skin or not enough?
