2013 Oscars Countdown! Play Crop Dead Gorgeous and Guess the Red Carpet Star

We're going to be playing this game on Sunday, but we've got a sneak peak for you here!

On Oscar Sunday's Countdown to the Red Carpet, Giuliana Rancic, George Kotsiopoulos and Kelly Osbourne will be playing a game called Crop Dead Gorgeous (you might remember it from the Golden Globes) where they show a celebrity photo with black boxes covering key identifying elements.

Then, it's up to you to guess which star is hiding behind the boxes!

If you've been following the red carpet fashion coverage, you might be able to guess some of the celebs just by getting a glimpse of their gown. Some of the others, however, they've made a little bit more difficult!

Just in case you didn't catch the game the first time around—or you want some more practice before Sunday—we've got a sneak peak with some practice pics!

Click through the photos below to see if you can guess which famous face is hiding behind the black boxes.

And don't forget to watch the Countdown to the Red Carpet on Oscar Sunday, starting at 1:30 p.m. ET / 10:30 a.m. PT for more crop dead gorgeous fun!
