Red Carpet Arrivals

Best Actress nominee Sandra Bullock looked luminous in a metallic and lace Marchesa gown, Celestina clutch and Neil Lane diamonds. The Blind Side star wouldn't predict a potential win, but she did express worry over reports that the Oscars stage could prove tricky for stars in stilettos. The star, in Jimmy Choo platforms, said, "If I step up on that stage tonight, I just don't want these heels to pull this body down!" she said.

Best Supporting Actress nominee Penelope Cruz looked ravishing in a bordeaux duchess satin draped gown by Donna Karan. "They made it for me," the actress admitted. The Nine star complemented her ensemble with Sergio Rossi black satin heels, a buckled Roger Vivier clutch, pear-shaped diamond drop earrings and stacked diamond bracelets by Chopard.

Avatar beauty Zoe Saldana wore a fresh-from-the-runway couture gown from Givenchy by Riccardo Tisci with the designer's violet suede shoes and Lorraine Schwartz amethyst jewels. The purple ombre design combined a sparkling bodice with a sculptured tulle skirt.

Crazy Heart nominee Maggie Gyllenhaal chose Fred Leighton jewels to go with a satin column gown from her friend Dries Van Noten. "He designed my wedding dress," said the actress, who had difficulty choosing between the three Oscars options offered by the designer. "I couldn't decide until late yesterday."

Inglourious Basterds star Diane Kruger looked elegant in head-to-toe Chanel. Her couture gown was made of layers of embroidered chiffon and featured an elegant black lace neckline. Kruger accented the cream and black gown with Chanel's black and white diamond "Camelia Nervure" brooch (elegantly pinned in her hair), the "Spirale" diamond ring, white gold and diamond "Camelia" studs and a Jaeger-LeCoultre diamond bracelet timepiece.

Best Actress nominee Helen Mirren glistened in a beaded silver satin crepe and tulle Badgley Mischka gown, clutch and shoes. The Last Station star topped off her look with a 125-carat oval-shaped diamond necklace and drop earrings by Chopard.

Amanda Seyfried wowed in Giorgio Armani Prive's sculptural sea foam green silk gown, Brian Atwood sandals, a metallic Salvatore Ferragamo clutch and an armful of dazzling bangles from Lorraine Schwartz. The intricate design featured a structured Swarovski crystal bustier and a full skirt made of mesh panel overlays.

She was a standout in a ruffled fuchsia gown from Marchesa, Fred Leighton jewels and Christian Louboutins, but Up in the Air star Vera Farmiga claimed that when it comes to daily life she lives under the radar. “No one ever recognizes me,” the Best Supporting Actress nominee said. “I had to tell my driver I was nominated for an Oscar!”

With her Grammy Award-winning husband Robin Thicke on her arm, Paula Patton looked stunning in an orange faille gown by Carolina Herrera, gunmetal Sergio Rossi peep toe pumps, a Judith Leiber clutch and Martin Katz jewels. Her film Precious: Based on the Novel Push by Sapphire was nominated for Best Picture.

Presenter and Avatar star Sigourney Weaver matched the red carpet in an elegant one-shoulder dress from Lanvin, accented with a Neil Lane brooch, Jimmy Choo shoes and simple black bow at the waist.
