Post Malone warned fans about his singing abilities in the middle of his Gov Ball performance

• Post Malone performed at Governors Ball music festival in New York on Sunday.
• Just before playing his hit song "Circles," he told the crowd he "can't sing without autotune."
• "If I sound like shit, it's not my fault. Someone spilled some beer on the computer or something."

Post Malone delighted fans on Sunday as the final headliner for Governors Ball music festival in New York City, using both a set list stuffed with massive hits and a hefty dose of humility.

Just before the Grammy nominee performed his No. 1 hit "Circles," he took a moment to warn the crowd about his limited vocal range.

"Everyone here knows I can't sing without autotune, right?" Malone said.

"If I sound like shit, it's not my fault," he added. "Someone spilled some beer on the computer or something."

Malone was similarly self-effacing throughout his hour-long set, which was scheduled to begin at 8:45 p.m.

Instead, Malone took the stage at 9:05 p.m., telling fans: "I'm here to sing some shitty songs and get fucked up."

Shortly after playing his opening song, "Wow," he chugged a drink in a red cup at the urging of the crowd.

Later, just before launching into an acoustic version of "Stay," he joked that it would be "the most boring part of the show."

"If you have to take a piss, go now," he said as the crowd laughed. "I've been fucking up a lot of songs tonight, I hope I don't fuck this one up."

The performance ended slightly after the event's cut-off time of 10 p.m. Malone told fans he was being asked to wrap up, but decided to play his two final songs regardless, "Rockstar" and "Congratulations."

Gov Ball also featured performances by Megan Thee Stallion, A$AP Rocky and Billie Eilish.
