Post Malone Revs Up Chelsea Afterparty Scene With Jason Momoa After London Show

Post Malone kept the party going after his sold-out London show, throwing an epic afterparty at The Rex Rooms in Chelsea on Sunday night. The American rapper, whose Big Ass World Tour has been touring the UK, appeared to cap off a blockbuster week of celebrity appearances at the celebrity-favored venue.

The Rex Rooms’ co-owners, fashion designer Marc Jacques Burton and producer Jason McNab, were in attendance along with actor Jason Momoa, as Malone lingered inside the club’s Meili main room into the early hours. The gathering followed a performance that had fans roaring at Tottenham Hotspur Stadium, where Malone delivered a high-energy set before heading to the Chelsea hotspot to continue the celebration.

Other attendees at the afterparty included actress Jodie Turner-Smith, known for Tron and The Acolyte, Rain Spencer from The Summer I Turned Pretty, and Paddy Gibson, along with NBA star Kyle Kuzma and luxury stylist Luxury Law, who is recognized for her work with Zendaya. The event type and guest list underscored The Rex Rooms’ status as a premier destination for celebrity gatherings.

Bottles of high-end beverages flowed through the night, with items including Meili Vodka from Momoa, Belvedere 10, Armand de Brignac champagne, and Tom Holland’s Bero non-alcoholic beer making appearances at tables across the club’s spaces, including exclusive rooms like the Kings 1942 Room. The night’s energy mirrored the venue’s ongoing reputation for attracting A-listers at the height of the entertainment calendar.

The weekend at The Rex Rooms reflected a broader pattern of high-profile visits to the Chelsea venue. Leonardo DiCaprio kicked off a wave of star power on Monday with an epic session ahead of his film premiere, joined by Benicio Del Toro and Tobey Maguire, while Saturday had already seen the launch of Tom Holland’s Bero. The club’s ownership group—Burton, McNab, and Momoa—has helped cement its place as the capital’s most in-demand celebrity venue, a status it has reinforced with a string of marquee appearances this month.

In related fashion news, Malone has been expanding his creative footprint beyond music. Earlier this month, he launched his eponymous Austin Post clothing line, a move that broadened his presence in fashion circles. The brand’s debut included a presentation at an event hosted in Paris at the Hôtel de Bourdon—Maison Pozzo di Borgo, with Malone presenting a collection that drew on a Western-meets-Americana aesthetic. A statement accompanying the launch described the line as a soulful extension of Malone’s identity, weaving together his Texas roots with luxury and exploration of global fashion narratives. Malone discussed the collaboration with GQ, noting his experience in fashion and his interest in blending music, style, and branding in a cohesive way.

As Malone continues his UK tour, Chelsea’s Rex Rooms appears to be aligning with the same star-studded trajectory that has characterized its recent weeks, reinforcing its place in the city’s celebrity nightlife curve. The afterparty’s guest list and the visible presence of internationally known names highlight how concert tours in Europe often culminate in high-profile, by-invitation-only events that extend the cultural footprint of a single show into a broader entertainment moment.
