Grammy Awards Fashion Face-Off: Rihanna vs. Carrie Underwood

Some style showdowns are lopsided. Ke$ha and Heidi Klum? Come on. The eccentric singer is going to get blown out of the water faster than you can say Tik Tok.

Rihanna vs. Carrie Underwood is a tougher one to handicap, however.

Nominated for best rap collaboration with Jay-Z and Kanye West, Rihanna paired her usual fiery hair with an Elie Saab Haute Couture gown, Neil Lane diamond earrings, bracelet and rings mixed with two Diamond in the Rough rings.

Sorry you weren't there, Matt Kemp. But she looks great in photos!

Carrie, meanwhile, recently got engaged and looked the part of a would-be bride last night in a Georges Chakra gown with silver leather straps. Just gorgeous.
