Rihanna was fashionably late to the Met Gala, arriving in a couture coatdress with a beanie and diamonds

• Rihanna was late to arrive on the Met Gala red carpet on Monday night.
• She wore black from head to toe, sporting a couture coatdress with a beanie hat and diamonds.
• Rihanna posed for photos with her boyfriend A$AP Rocky, who wore a multicolored quilt over a suit.

Just when we thought Rihanna wasn't going to show up to the Met Gala, she arrived on the red carpet fashionably late.

And Rihanna made sure to go bold for her first Met Gala in three years.

The Fenty founder wore black from head to toe for the "In America: A Lexicon of Fashion" theme, sporting a couture Balenciaga coatdress designed by the brand's creative director Demna Gvasalia, according to Vogue.

Rihanna's full-length, puffy coat featured a dramatic collar. She paired the ensemble with a beanie hat, a crystal headpiece, and a glittering diamond necklace.

In a rare move for the beauty mogul, Rihanna walked the red carpet and posed for photographs with her boyfriend A$AP Rocky.

The rapper wore a patterned multicolored quilt - which featured yellow, blue, red, green, and brown squares - designed by ERL that stood in complete contrast to Rihanna's monochromatic ensemble.

He later took off the quilt to reveal a suit underneath, much to Rihanna's delight.

Rihanna - who is expected to host an after-party for Monday's event, according to Page Six - hasn't appeared at the Met Gala since 2018, when she wowed in an outfit inspired by the pope.

Her sparkling ensemble, which took 250 hours to sew and 500 hours to hand-embroider, perfectly fit the "Heavenly Bodies: Fashion and the Catholic Imagination" theme.
