54TH ANNUAL GRAMMY AWARDS ARRIVALS......

We see London, we see France! The Black Eyed Peas singer gave everyone a peek at her black bra and panties thanks to her neon orange lace Jean Paul Gaultier Couture gown. We give her credit for pushing the envelope with the see-through number, but the Halloween color scheme was downright frightening.

Rihanna took the plunge -- with her neckline that is -- at the 54th Annual Grammy Awards on Sunday night. The newly-blond singer heated up the red carpet in an extremely sexy black silk gown she designed herself along with Giorgio Armani. RiRi revealed that the dress was inspired by Michelle Pfeiffer in “Scarface.” On her feet? Christian Laboutin PVC accented pumps.

Long gone were the country cutie’s trademark curls! For the Grammys, Taylor Swift slicked her hair back into a chic bun, which was the perfect understated ‘do to let her show-stopping Zuhair Murad mermaid gown do all the talking. To add to the gold rush, the Grammy-nominated singer accessorized with Neil Lane earrings.

Twinkle, twinkle! The country superstar lit up the red carpet in a stunning Gomez-Gracia long-sleeve backless “Starlet” gown, which featured intricately-embroidered sequins, offset with a black Rene Caovilla clutch.

Why so blue? Katy Perry matched her Elie Saab Couture gown to her post-Russell Brand hair color. But that wasn’t the Grammy nominee's only faux pas. The pop star traded in her usual sexy style for a look better suited for a grandma -- not a newly-single woman. Even $2 million worth of Norman Silverman jewels couldn't save this ensemble!

Surprisingly, the hotel heiress looked quite sophisticated and chic in her beaded white-and-gold Basil Soda gown. Well done, Paris!

The queen of the Grammys, who won a whopping six awards, hit a high note in a sequined black Armani gown with three-quarter sleeves and Harry Winston jewels. Adele also strayed from her usual 60s-style bouffant and instead opted to sport a sleek strawberry blond ‘do and bright-red lips, which really perfected the entire look.

Usually dressing like a disco ball would be considered a bad thing, but not for the “Domino” singer, who sparkled in a Julien Macdonald creation adorned with mirror-like appliqués and accessorized with a Lulu Guinness Perspex Lips clutch.

Arguably the best-looking couple of the night, Alicia Keys and her husband Swizz Beatz managed to perfectly meld funky with glam at the Grammys. While the R&B singer vamped it up in an Alexandre Vauthier Couture fitted LBD with padded shoulders and a very ornate gold choker, her producer-hubby dared to rock a purple delvet blazer 

The Maroon 5 singer and “Voice” coach channeled "Mad Men's" Don Draper in his gray suit, blue tie, and polka-dot pocket square. But while Mr. Levine classed up the red carpet, the same can’t be said for his Victoria’s Secret model-girlfriend, who wore what could be best described as half of a dress.

Between Wiz Khalifa's white-and-black tuxedo jacket, tats, and pot leaf necklace and Amber Rose's high-cut electric yellow Versace number and buzzed hair, the engaged couple was one to watch on the red carpet! How sweet was it that the model picked to wear a color to honor her beau’s Grammy-nominated rap performance, “Black and Yellow”?

The former Destiny’s Child member gave the Grammys a touch of uber-glam in an Alberta Ferretti gown embellished with a silver appliqué on the bodice. For an added touch of sparkle, Rowland accessorized with Lorraine Schwartz jewels on her ears and fingers.

The legendary diva -- who won a Lifetime Achievement Award -- jazzed up her pantsuit with blinged-out cuffs and a sparkly broach.

Holy heck! What was the rapper thinking when she stepped onto the red carpet in a hooded Versace cape embellished with the label’s Medusa head ... escorted by a Pope look-alike? Ms. Minaj is known for her wacky sense of style, but surely the fashion gods were angry about this particular getup.

Is Cyndi Lauper a vampire? At 58, she certainly doesn’t seem to age, but does she really need to dress like one? The “Girls Just Want to Have Fun” singer sported a double-breasted suit by Jean Paul Gaultier, which featured chains and a daring slit. Black-and-blond hair completed her goth-like look.

The two-time Grammy nominee opted for a plain white tee and high-waisted asymmetrical skirt that looked more like a giant napkin. If that wasn’t bad enough, she topped it all off with brown platform boots. Looks like someone could use a stylist!

The “Jersey Shore” star flaunted her svelte physique in a zebra-print dress by BB Addiction and bright white platform shoes. Unfortunately, she topped off her look with a big netted black bow. Who does she think she is -- Minnie Mouse?

While most folks didn’t know the Russian electronic artist when she hit the red carpet in her fitted pink gown, everyone was buzzing about Sasha Gradiva after she walked by thanks to her, um, interesting accessory: a “Terminator”-like machine gun arm. Though she claimed she was making a statement against war, next time she should leave her weapons at home!
