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