John Mayer really knows how to come across as a jack ass and it seems the adult film industry is keen to have the filth bag on board.

John was busy last week, ranting about Jennifer Aniston, Jessica Simpson and generally talking dirt in Playboy. However, the singer also had time to let us all know that his dream job would be writing pornography.

Now it seems an adult entertainment company are seeing if the mouthy singer will put his money, where his something that rhymes with gob, is.

Vivid Entertainment have written a letter to the singer, offering him a job writing and directing one of their upcoming films.

Let's hope John hangs up his guitar for good and stops abusing all our ears with his garbage. By that we mean his sorry excuse for pop music and not his foul magazine rants...
