Just days after launching his new fashion brand, Austin Post, with a runway show in Paris, Post Malone surprised fans at Paris La Défense Arena on Wednesday night (September 3) by bringing out Chris Stapleton to perform “California Sober” together for the first time on his Big Ass Stadium Tour. The unexpected collaboration highlighted the duo’s close creative partnership as they delivered the Southern rock standout from Post’s chart-topping 2024 album, F-1Trillion, with Stapleton joining Post at his big Paris show even though he is not currently on tour in Europe. The show also featured opener Jelly Roll joining Post for their duet “Losers,” which has become a fan-favorite on the tour. Post Malone and Jelly Roll will continue their European run together on the Big Ass World Tour with a two-night stand at London’s Tottenham Hotspur Stadium on September 7-8. (Holler)
