Met Gala 2023: Rihanna, A$AP Rocky walk carpet together

Rihanna arrived in style at the 2023 Met Gala Monday night.

After much anticipation, the "Diamonds" singer arrived on the Met Gala carpet with her boyfriend, rapper A$AP Rocky.

Rihanna wore a stunning white floral gown -- reminiscent of a wedding dress -- in accordance with this year's theme, "Karl Lagerfeld: A Line of Beauty," which was dedicated to the longtime Chanel creative director, who was known for creating iconic bridal looks for the luxury fashion house.

Rihanna's dress boasted large, structural white flowers that draped around her head like a hooded cape.

She accessorized the look with dark sunglasses.

A$AP Rocky donned a black dress coat with a red tartan kilt, which included a train, and embellished jeans underneath. He finished the ensemble with a stack of Gucci belts and a thin black tie.

Rihanna is known for serving iconic looks at the annual Costume Institute Benefit.

In 2018, when she served as a Met Gala co-chair, Rihanna donned a papal-inspired ensemble adorned with pearls and crystals, which was a nod to the night's theme, "Heavenly Bodies: Fashion and Catholic Imagination."

In 2021, when she attended with her boyfriend A$AP Rocky, Rihanna arrived in a custom look styled by Demna Gvasalia, according to Vogue. The all-black ensemble -- a floor-length Balenciaga coat and Stephen Jones Millinery hat, accessorized with a diamond headpiece and matching necklace -- was an interpretation of all-American style for the theme "In America: A Lexicon of Fashion."

But it was perhaps the yellow Guo Pei gown that she wore to the 2015 Met Gala that cemented her as one of the event's most anticipated celebrities to watch for on the carpet. The Fenty Beauty founder and CEO told Vanity Fair at the time that the gown took two years to make.

Rihanna's Met Gala appearance Monday night comes amid a whirlwind year for the singer.

In February, the singer delivered an electrifying Super Bowl halftime show performance, during which she sang some of her biggest hit songs.

Following her performance, her rep confirmed to ABC News that she is pregnant with her second child with partner and rapper A$AP Rocky.

Rihanna was also recently nominated for both a Golden Globe and Academy Award for the song, "Lift Me Up," which she co-wrote with Ludwig Göransson, Ryan Coogler and Tems for the film "Black Panther: Wakanda Forever."
