Blake Shelton says it happened. Justin Moore swears it never did, but then again, he admits he wasn’t exactly in a remembering state of mind.

The two singers teamed up for their first-ever duet on Moore’s This Is My Dirt album. The song “Beer Ain’t One” will remind music fans of Jay-Z‘s “99 Problems” from 2003, except Moore/Shelton have “99 problems, but a BEER isn’t one.” 

“Those are the ones that you go, ‘Are you sure somebody ain’t wrote that? Are we stealing something from somebody?'” Moore tells Taste of Country Nights.

• Casey Beathard, Jeremy Stover, Joe London, Justin Moore and Will Bundy wrote “Beer Ain’t One.”
• Moore tells Evan Paul that when he heard the song he thought, “that’s as Blake Shelton as it gets.”
• Duets with Randy Houser and Dierks Bentley are also included on This Is My Dirt.

Listen to the full song below. It presented a chance for Moore to tell a good story about his longtime friend, and host Evan Paul took it.

“I mean, he’s always drunk,” Moore says of Shelton. “I think maybe that’s why you don’t get many good stories.”

Paul has tried — and failed — to get stories about Shelton from other artists who stop by.

Quips aside, Moore recalls Shelton getting him a performance spot on the finale of NBC’s The Voice about 10 years ago. “Lettin’ the Night Roll” was his single, if you want to date it. A contestant was a fan, so it all made sense.

“And so Blake was like … ‘How you getting home?’ I said, ‘Well, I’m flying out tomorrow’ and he goes, ‘Well, you can just ride with me,'” Moore shares.

The two singers and their respective tour managers boarded this private plane and got to drinking.

“And I have a lot, you know,” Moore says. “(I’m) trying to keep up with him, but he’s only like 7 ft. 12″ or something, you know … and so I pass out.”

Shelton gets dropped off in Oklahoma, and the pilot flies Moore to Arkansas. No big deal right? Uh, wrong.

Here’s Moore one last time:

“And he swears up and down that I threw up in the plane. And it was a NASCAR driver buddy of his that owned the plane,” Moore says. “He’s like, ‘I’m telling you, man, he said you puked in his plane.'”

“And so he has maintained that to this day, and that’s been over a decade,” he continues, explaining that Shelton blames him for puking in the sky. “I still don’t think it happened.”
