Latest John Mayer rumor involved him hooking up with a certain Kristen Cavallari. There was a Page Six Blind Item recently that claimed there was a famous singer who has been sleeping with a reality star in secret for two years.  It was taken a bit further and announced by “sources” that the couple were in fact together – and considering going public.

Well, John steps in – and denies the whole thing via Twitter, rather humorously I might add.
