Post Malone had some help from Shaboozey when he headlined the final night of Stagecoach on Sunday evening (April 26).

Wallen was unable to attend the music festival in California, so the F-1 Trillion artist surprised the audience when he brought Shaboozey on stage to perform “I Had Some Help.” Post Malone included the hit single on the country studio record he released in August 2024. The project also included collaborations with Tim McGraw, Hank Williams Jr., Blake Shelton, Dolly Parton, Lainey Wilson and many others. PEOPLE shared a clip of Post Malone’s Stagecoach performance with Shaboozey on Instagram. Watch it here.

Shaboozey is part of the star-studded lineup of the 2026 iHeartCountry Festival, along with Carly Pearce, Luke Bryan, Kane Brown, Parker McCollum, Riley Green, Dylan Scott, Russell Dickerson, Gretchen Wilson, Lauren Alaina and Chase Matthew, plus special guest George Birge. iHeartRadio's Bobby Bones is returning as the 2026 iHeartCountry Festival’s host. The show will take place on May 2 at Moody Center in Austin, Texas. Tickets to the show are available on Ticketmaster.com. Fans across the country will be able to catch all the action as the 2026 iHeartCountry Festival will be broadcast live across iHeartCountry stations nationwide and the free iHeartRadio app on Saturday, May 2nd at 8pm ET/5pm PT (7pm CT).
