Aerosmith front-man Steven Tyler recorded a song with Psy, the Gangnam Style guy.

Psy broke the news to Vogue.  He told the magazine, "I just finished recording my next song with a legendary artist, Steven Tyler from Aerosmith.  When I was in middle school, I literally cried when they were singing Crazy or Amazing or whatever, they were my lifetime role models."

Aerosmith is not the only rock band that Psy enjoys.  He also says he 'had a huge rock band mania" and cites bands like Queen, Bon Jovi, and Guns N' Roses.

He also mentions that the late Queen front-man Freddie Mercury is his "life role model."
