Lainey Wilson appeared as a surprise guest when Post Malone celebrated the grand opening of his bar on Wednesday night (October 8) in Nashville, Tennessee.

Post Malone introduced Wilson to the stage to perform “Nosedive,” a collaboration that appeared on Posty’s highly-anticipated country album last year, F-1 Trillion. The record also included collaborations with Tim McGraw, Hank Williams Jr., Morgan Wallen, Blake Shelton, Chris Stapleton, Dolly Parton, Luke Combs, Jelly Roll and more. Wilson was one of several surprise guests throughout the show, which shut down Nashville’s Lower Broadway with thousands of fans in attendance. Others included Dierks Bentley and Brooks & Dunn. iHeartRadio’s Nashville-based 107.5 The River shared a clip of Post’s performance with Wilson on Instagram, hailing the event “nothing short of amazing!”

Posty’s officially opened its doors on July 2. The 26,000-square-foot bar and entertainment venue includes six bars, three stages and three floors, with a VIP lounge, karaoke, a rooftop patio and more. It’s open at 305 Broadway. Post Malone said in a previous statement that “we’ve created a space where everyone can come together and kick some a**. Nashville has really become a second home for me so I can’t wait to invite y’all over to my house.”
