Blamed best friend when Wife found porn, Please RATE!

Blamed best friend when Wife found porn, Please RATE! My wife found porn in my web browser's history and I immediately blamed my best friend. Now she thinks my best friend is a pervert and has asked me to have a talk with him. I spent two hours explaining to her why we can't control my friend's porn habits. I lied to my wife & now my best friend (already considered a bad influence) is now considered to be even more so. Need your guidance, Please RATE!
