Tim McGraw got in the face of two hecklers during his Saturday night performance at the Nugget Event Center in Reno, Nevada.

The incident began after the country crooner, 54, appeared to fumble the lyrics of his song Just To See You Smile, prompting some people to boo, as seen in video obtained by TMZ.

McGraw became agitated, standing up and sticking out his chest before hopping off the stage and into the crowd to get into one particular pair's faces.

Tim first tried to rise above their haranguing, but then asked the audience why they were mocking him.

He added that people were welcome to leave if they weren't enjoying his set.

Then things escalated as the husband of Faith Hill jumped off the stage, and got in the couple's face to share some strong words.

McGraw wasn't the only one that was upset either, as many other fans were miffed that the show was interrupted.  

He went on to explain why he was a little out of sorts, telling the crowd he has been shooting the Yellowstone prequel Y: 1883 for the past two days and was beyond exhausted, hence the forgotten lyrics.

'If I forget words tonight, just know I'm old.' he said with a laugh. 'And I'm shooting a movie and I'm working with my wife.' 

'There are a lot of variables in that situation. So, if I forget the words, sing along with me and help me out,' he went on.

Afterwards, McGraw went on with the show. It's unclear what happened to the couple that was harassing him.

McGraw will appear in Y: 1883 with wife Hill, Billy Bob Thornton, and Sam Elliot.

The story follows the hit NatGeo show's Dutton family as venture west across the Great Plains.

Y: 1883 is set to premiere December 19th, 2021 on National Geographic.
