Tim and Faith’s Girls Learned Lesson from Kanye West

If there's a silver lining to the Kanye West cloud, it's that kids learned a lesson in manners and humility. As angry as Tim McGraw was that the rapper hijacked Taylor Swift's VMA speech, he says he was glad for the conversation he had with daughters Gracie, Maggie and Audrey after the incident.

"He shows himself to be an idiot every time he does stuff like that," Tim tells 'CMT Insider' (via PEOPLE). "[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."

Still, Tim was fired up by Kanye's antics. He just didn't let his girls see it. "When they weren't looking I said, 'He needs an a-- whoopin'!" Tim adds.

CMT's interview with Tim airs this Saturday, Sept. 19 at 1:30 PM ET.
