WATCH: Post Malone Shocks Crowd by Bringing Out Chris Stapleton in Paris, France for ‘California Sober’

Just days after launching his first ever fashion brand, Austin Post Apparel, Post Malone graced the stage at France's Paris La Defénse Arena for a blockbuster, star-studded show.

Attendees were treated to an unexpected cameo from ‘Tennessee Whiskey’ hitmaker, Chris Stapleton, who emerged to perform ‘California Sober’ alongside his buddy Post.

It marks the first time the two chart titans have performed the track on the latter's Big Ass Stadium Tour, with the playful, Southern Rock-infused earworm serving as one of the many stand-outs from Post Malone's stellar 2024 studio album, F-1Trillion.

Their warm friendship radiated throughout the performance, with Stapleton and Post grinning at one another as they delivered the bittersweet, tongue-in-cheek tale.

The fact that Chris Stapleton is not in the middle of a European tour made this link-up all the more surprising, with the Kentucky native seemingly flying out especially for this set. Elsewhere during the show, Jelly Roll once again came out to perform ‘Losers’ with Post, a duet that has become a much-loved nightly tradition on the tour.

Earlier in the week, Post Malone launched Austin Post Apparel with an exuberant, Western-themed fashion show at Lagerfeld Mansion in Paris. The spectacular event concluded with a model dressed as a cowboy riding into the venue on a horse.

On Sunday and Monday, Post Malone and Jelly Roll bring their Big Ass Stadium Tour to London, UK, with a highly anticipated double-header at Tottenham Hotspur Stadium.
