Salma Hayek Pinault, Alfonso Cuarón, and Alejandro González Iñárritu are set to co-host London’s exclusive Serpentine Summer Party this year.

On June 23, at the iconic gallery’s most important annual fundraiser — ensuring exhibitions and artist projects remain free and open for all — the event will be hosted by Michael R. Bloomberg, Chairman of Serpentine’s board of trustees; Bettina Korek, CEO; and Hans Ulrich Obrist, artistic director.

They will be joined by the world-famous Mexican film stars in Kensington Gardens, The Hollywood Reporter can reveal, in what will mark the 25th Serpentine Architecture Pavilion — an architectural commission that began with Zaha Hadid, Frank Gehry and Oscar Niemeyer in 2000, and has since become one of the most significant platforms in the world for introducing emerging and mid-career architects to a global audience.

The 2026 Pavilion, titled a serpentine, is designed by Mexico City-based practice LANZA atelier. They chose brick as their primary material, creating a rhythmic structure that moves from opaque to permeable: a bridge, they say, in architecture and in spirit, between the U.K. and Latin America.

“Throughout my career I have been driven by a belief that Latin American voices, stories and creativity belong at the centre of global culture, not at its edges,” said the Oscar-nominated Hayek Pinault. “The Serpentine Pavilion has always understood this. When I visited Frida Escobedo’s Pavilion in 2018, I felt it immediately — a Mexican architect in conversation with one of the world’s great parks, on her own terms. LANZA atelier’s a serpentine continues that dialogue, and I am honored to be part of celebrating it.”
