We're officially dubbing the "Love on the Brain" singer this year's Met Gala queen! No one dressed to the theme of "Rei Kawakubo/Comme des Garçons: Art Of The In-Between" better than RiRi, who wore a sculptural Comme des Garçons number straight off the Fall 2016 runway. Her lace-up red heels were the perfect finishing touch.

The model opted for a head-to-toe nude ensemble for this year's fête, turning heads in an asymmetrical Tommy Hilfiger dress, thigh-high fishnets and stilettos. We give this monochromatic look an A+!

All eyes were on The Life in a Year star as she made her entrance on the Metropolitan Museum of Art's red carpet Monday night in an intergalactic getup that had everyone talking. The model debuted her bald new 'do by coating her head with metallic silver paint and sequins. She completed her look with an embroidered iridescent silver organza jacket and pants by Chanel.

Leave it to the 58-year-old singer to sport one of fashion's biggest night's craziest looks. The singer wore an Army-inspired outfit, which consisted of a camouflage Moschino dress, flak jacket, fingerless black leather gloves and multiple gold statement necklaces.

The fashionista does it again! The Shallows star (and eight-time Met Gala attendee) rocked a plunging gold Versace gown, which featured ombre blue feathers cascading down the train. She completed the stunning look with jewelry from Lorraine Schwartz and Ofira Jewels.

The reality star flaunted her petite figure and bared her booty in an embellished black thong and sexy, sheer couture dress by La Perla. Her red pout and Christian Louboutin heels pulled the look together perfectly.

We barely recognized the Rules Don't Apply star when she stepped out to the red carpet, as she was sporting a chic black bob with bangs and gothic makeup consisting of high-volume lashes and a strikingly dark lip. But the poofy pink skirt on her strapless dress gave the entire ensemble a more feminine feel.

Girls just wanna have fun, and that's exactly what the actress did with her outfit on Monday night. Dunham, who normally opts for less showy looks, pulled out all the stops, rocking a checkered black-and-maroon Elizabeth Kennedy dress that featured a full skirt and was adorned with a Planned Parenthood pin.

The "Bon Appetit" singer went all out with the soiree's theme, making her grand entrance in a bright red Maison Margiela 'Artisanal' dress designed by John Galliano. She amped up the quirky look by adding a sheer red silk veil, intricate "Witness" headpiece and red leather heeled boots.

Hot mama! The model went with white for the fashion party, showing off her curves in a bodyhugging floral and embroidered Marchesa gown that undoubtedly made a statement. She amped up the glam by slicking her hair back and highlighting her cheeks with light pink blush.

For the first time ever, the singer attended fashion's biggest night, and her debut did not disappoint! Dion wore a silver-and-black custom Versace number and an oversized black headpiece that would make Met Gala veteran Sarah Jessica Parker proud.

Donning a beige Ralph Lauren Collection custom trench coat evening gown with black heeled booties, the Baywatch star proved she really can make anything look sexy. It was one of the most unique looks we saw on the carpet, but she pulled it off impeccably.

Also making her Met Gala debut, the actress slayed in a custom-made Atelier Versace beaded black jumpsuit, which featured a full black skirt with gold detailing. Keeping full focus on her sexy ensemble, she opted for a simple low bun and bedazzled headband.
