Tim McGraw is the latest in a band of celebrities, including Pink, Kelly Clarkson, and even President Obama, sounding off on Kanye West’s treatment of teen country star Taylor Swift at Sunday night’s MTV Video Music Awards.

The country crooner, who was the subject of Taylor’s debut single, has some harsh words for the hip-hop heavyweight in an episode of CMT Insider, airing this Saturday, Sept. 19.

“He shows himself to be an idiot every time he does stuff like that,” Tim says, adding that Kanye’s ill-mannered outburst served as a learning lesson for daughters Gracie, 12, Maggie, 11, and Audrey, 7. “[My girls] were upset. But what he did do is provide a great example of how not to be, and my girls learned a big lesson.”

He added, “When they weren’t looking I said, “He needs an a– whoopin’!”
