First off Katy must really like her heart broken because now she is linked to the well traveled (at least in Hollywood) John Mayer.  Perry just finalized her divorce from Russell Brand earlier in July.  Mayer loves those pop singers like:  Taylor Swift and Jessica Simpson to name a few.  This is definately a recipe for disaster, and Katy might have to deal with her dirty laundry being aired in a song, or vice-versa. 

How long do you give this couple, before splitting up?
