Johnny Depp and Steven Tyler joining forces? This could be incredibly awesome or horribly disastrous. 

Johnny Depp confirmed to Extra that he and Steven Tyler are collaborating on a song. Depp says he is a long time of Aerosmith and is really looking forward to the project saying it is a "dream come true."

Steven Tyler says that the admiration is mutual, confirming to spinner.com that he would love it if Johnny Depp would play him if there were ever a movie made about Aerosmith.

This is not the first time Depp has crossed paths with rock greatness. He co-starred with Rolling Stones guitarist Keith Richards in Pirates of the Caribbean: At World's End and is currently directing a Keith Richards documentary.

Both Steven and Johnny are busy right now. Steven is a judge on the current season of American Idol and has a new solo song out, plus he just released his book, Does The Noise In My Head Bother You? Depp's new movie, Pirates of the Caribbean: On Stranger Tides hits the big screen May 20.
