The couple attended their first Met Gala on Monday celebrating the late Karl Lagerfeld.
Brosnan rocked a tailored Tom Ford suit and matching shades, while Smith looked glamorous in a black Monique Lhuillier gown.
Shockingly, Monday marked the couple's first time attending the star-studded event and they expressed excitement at being included in the festivities, which this year celebrates the late fashion designer Karl Lagerfeld.
"This is our first time. Our very first time," Brosnan confirmed to ET's Rachel Smith. "Why not if not now, when?"
"It's such a great occasion. Mr. Karl Lagerfeld, he was someone that we both admired and someone who a number of years ago came and took our photographs and our children's photographs," he continued. "So to be invited is just delightful occasion. A celebration."
The co-chairs for the 2023 event are Michaela Coel, Penélope Cruz, Dua Lipa, tennis pro Roger Federer, and Vogue editor-in-chief Anna Wintour. The annual gala is a fundraiser for New York City's Metropolitan Museum of Art.
