Red Carpet Arrivals

Adele

played up her voluptuous curves in a three-quarter sleeve black sequined Giorgio Armani gown, De Beers earrings and a 12.4 carat diamond ring by Harry Winston. The singer, nominated in six categories, will perform tonight for the first time since undergoing throat surgery for a hemorrhaged vocal chord.

Carrie Underwood

looked flawless from all angles in a backless Gomez-Gracia long-sleeve gown that she accessorized with diamond danglers and a Rene Caovilla clutch.

The "Firework" singer, up for both Record of the Year and Best Pop Solo Performance, walked the red carpet in a sky blue Elie Saab Couture gown and Norman Silverman diamonds.

Though the singer hadn't watched Christian Siriano's Project Runway season, she became a fan of the designer after catching his collections. "I saw this dress at the last Fashion Week and was very pleased to have an occasion to wear it," the Best R&B Performance nominee said of her ruffled LBD.

"I had two choices and this was the safe one," Fergie said of her Jean Paul Gaultier tangerine couture lace dress, which she accessorized with Neil Lane jewelry. And given it was so revealing, the Best Rap/Sung Collaboration nominee had to prep properly: "I've been doing a lot of juicing and sticking to my Diet Designs delivery service," she confessed. "It's music's biggest night, so I had to come and make a splash."

Already the recipient of a Grammy for Best Country Solo Performance, Taylor Swift looked every bit a winner in her silk Zuhair Murad mermaid gown and gold Neil Lane jewelry. "It's one of my favorite dresses I've gotten to wear," she said of the embroidered dress. "I saw it months ago, and I said 'We've got to save this for the Grammys.'"

E! News host Giuliana Rancic interviewed the top names in music wearing a black satin asymmetrically draped cocktail dress cinched with a gold metal belt by Georges Chakra Couture, an Isharya ring and H. Stern earrings.

Rihanna

wowed in a sliver of a black Giorgio Armani dress she helped to design, adding a down-to-there V-neck and up-to-there slit. She accented the look with a Jimmy Choo clutch, Neil Lane jewelry, a Jacquie Aiche body chain and Louboutins.

Actress Taraji P. Henson, who made her singing debut in the movie Hustle and Flow, walked the red carpet in a sequined halter gown by Basler.

made an entrance in a sleek strapless Kaufmanfranco design with textured panels. She accented the detailed design with Vanessa Leu earrings and a simple metallic manicure.

Presenter and country star Miranda Lambert wore a cap sleeve Atelier Pavoni gown and Stuart Weitzman shoes. She finished the look with Tiffany & Co. jewels and clutch.

Best New Artist nominee Nicki Minaj arrived with a bishop in tow, coordinating his white priest's costume with her own devilishly scarlet Atelier Versace cape boasting intricate black beading.

Double nominee Robyn pumped up her white tee and asymmetrical skirt with platform lace-ups and edgy jewelry.

The Best Rock Album nominees looked dapper in slim suits, all from Gucci. Caleb Followill stood out from the pack in a neutral design and burgundy bowtie while Jared and Nathan Followill matched their dark ensembles.

Lady Antebellum's Hillary Scott celebrated the band's Best Country Album nomination in a strapless purple Monique Lhuillier gown. She completed her look with strappy Giuseppe Zanotti heels, Sutra jewels and a Kelian enamel clutch.

Kate Beckinsale

struck a pose in an ivory draped Zuhair Murad dress cinched at the shoulder with a black bow and Salvatore Ferragamo pumps. Beckinsale showcased her look's neckline with a voluminous curly updo and dangly Sutra earrings.

The YouTube sensations that stole hearts with their rendition of nominee Nicki Minaj's "Super Bass" graced the red carpet in their signature Barbie pink Ellen ensembles, topped off with golden crowns.

The hitmaker and one of the night's many performers chose a three-piece slate gray suit featuring pant cuffs that hit just above the ankle. "The Lazy Song" singer also injected some of his always-relaxed attitude by working a pair of round tortoise-shell shades.

Last year's Best New Artist winner Esperanza Spalding posed for photos in a dip-dyed gown cinched with a bronze belt.

Best Rap Collaboration nominee Kelly Rowland strutted her stuff in a creamy Alberta Ferretti design with silver applique on the bodice. The singer accessorized with Lorraine Schwartz jewels.

Actress Malin Ackerman walked the red carpet in a cutout little white dress from Cushnie et Ochs, Stephen Webster gems and cutout Chrissie Morris shoes.

The Maroon 5 frontman suited up for a performance with The Beach Boys and Foster the People in a blue and gray ensemble. Adam Levine mastered the mixed print trend in a striped button-down and polka-dot pocket square.

Lily Aldridge

stopped by the Grammys to cheer on her husband, Kings of Leon frontman and Best Rock Album nominee Caleb Followill. The model showcased her baby bump in a Gucci chiffon maxidress printed with oversize pansies, while a sleek updo, black pumps and Anita Ko hoop earrings finished off the look.

Best Country Album nominee Blake Shelton put his spin on the traditional three-piece suit by pairing a Ermenegildo Zegna black jacket and matching pants with a gray pinstriped vest. A black tie and slicked-back hair finished off the look.
