Plenty of people want to know who John Mayer wrote about in "Your Body Is a Wonderland" -- but asking him while he's with his current girlfriend is just bad form.
The Grammy-winning crooner was leaving the Waverly Inn in New York last night with gal pal Minka Kelly, when one photog (not, by the way, a TMZ guy) asked John about the famous song -- then proceeded to sing it. Mayer lashed back at the lensman, "Do you see that I am with a woman? Wow, that's terrible."
That last sentence applies to both the photographer's question -- and his singing.
