Billie Joe Armstrong's recent comments about Psy haven't led the South Korean rapper to be any less than a "gentleman." 

Earlier this week, the Green Day frontman posted a photo of the man behind the viral hits "Gangnam Style" and "Gentleman" on Instagram and referred to him as "the herpes of music."  He wrote, "Once you think it's gone, it comes back." 

Psy, whose new single has successfully moved him out of the category of one-hit wonder, decided to take the high road. 

In an interview with Fuse magazine, he took it as a compliment and actually thanked Billie Joe for comparing him to the infection.  He joked, "I kind of like it, it's cool."
