Vince Gill confronted members of the Westboro Baptist Church outside of his concert in Kansas City on Sunday.

The normally soft-spoken Vince, defended himself against protesters who was calling him an "adulterer." He also joked that the protestors weren't any of the church's leaders, but "the C-team."

A video of the incident has shown up on YouTube. Be warned -- there's some strong language and is NSFW or to be watched around kids.
