Red Carpet Arrivals

The ultimate glamour couple put in a rare red-carpet appearance in support of Pitt's Babel. Jolie wore a draped and pleated custom frock from St. John Knits that recalled the '60s designs of Madame Grès, and Pitt chose a classic tux by J. Lindeberg.

Smith, a nominee for The Pursuit of Happyness, blew a kiss to the crowd while squiring an Armani Privé-clad Pinkett Smith across the red carpet.

Looking tan and happy, the new parents shared a moment as they made the rounds. Garner was all '70s cool in her white Gaultier column gown with metallic accents.

The soulful pair made sweet music on the red carpet. Blige dazzled in a Reem Acra frock that matched her ruby-and-diamond jewelry, while Timberlake wore a sophisticated tux with a long tie.

The British beauty was definitely one of the belles of the ball in a silver-accented Marchesa gown with a dramatic train. She wore Private Collection Cartier jewels with her coronet of blond braids.

Lopez cuddles up to her husband in a sari-inspired Marchesa gown with gold embroidery. Her beautiful bijoux are by Lorraine Schwartz.

The angelic star of The Holiday looked divine in a white Valentino gown with tulle tiers.

The singer-actress proved that she could be both a Dreamgirl and a golden girl in her Elie Saab sequined gown. She was nominated for Best Performance by an Actress in a Motion Picture-Musical or Comedy (a category won by Meryl Streep).

Double-nominee DiCaprio wore a Giorgio Armani tuxedo, letting his best accessory be his piercing blue eyes. The actor competes against himself in the Best Performance by an Actor in a Motion Picture-Drama category for his work in both Blood Diamond and The Departed.

The duo went for pure Hollywood glamour-Barrymore in a shoulder-baring John Galliano for Christian Dior gown and Grant in a classic tux.

The Project Runway hostess brightened up the red carpet in her strapless white Givenchy gown and diamond choker-a 213.74-carat necklace from the Heidi Klum Collection for Mouawad. Husband (and nominee for Best Original Song) Seal would likely agree that even all those carats can't compete with the supermodel's super-smile.

The petite Housewife walked tall in a midnight-blue Ungaro gown with turquoise-embroidered straps. Her best accessory? An engagement ring from beau Tony Parker.

The Medium nominee wore a classic platinum-colored gown with some extra edge-a strapless leather bodice. Her sister (and date) donned a navy gown with peekaboo lace sleeves.

The Spanish star floated down the red carpet in light-as-air Chanel Couture. Cruz is nominated in the Best Performance by an Actress in a Motion Picture Drama for her role in Volver.

Big Love'

s trio of beauties showed off some serious personal style. Always the fashion plate, Chloë Sevigny wore a single-shouldered Yves Saint Laurent gown, while Ginnifer Goodwin went for the bronze in a satin Dolce & Gabbana stunner.

The TRL VJ dazzled in a gold satin gown with bejeweled straps and long, loose waves.
