George Clooney, Stacy Keibler At Oscars 2012: Couple Walks The Red Carpet (PHOTO)

George Clooney is up for an Oscar for Best Actor at the 84th annual Academy Awards, and he and girlfriend Stacy Keibler made a stunning splash on the red carpet before the show.

"I love when they say 'Who are you wearing?' ... You're carrying someone on your back," Clooney joked with E!'s Ryan Seacrest.

The actor, who always seems to be joking around on the carpet, later revealed he was wearing a tuxedo by Giorgio Armani, while Keibler was decked out in a gold Marchesa gown, along with Judith Leiber and Lorraine Schwartz accessories.

Clooney chatted with Seacrest about his film, "The Descendants," saying how lucky he was to be able to work with director Alexander Payne.

"I got to work with a really great director on a really great screenplay, and that's rare in your business," Clooney said.

Seacrest mentioned that he heard Clooney wasn't afraid of death or failure, and joked that Keibler wasn't afraid of anything.

"She's 7 feet tall. What's she afraid of?" Clooney joked. "She's afraid of low-flying planes ... She hit her head on the blimp."
