John Mayer has been asked to direct a porn movie.

The 'Gravity' singer - famed for his love of women and wild sex life - was approached by x-rated video giant Vivid Entertainment to write and produce one of their upcoming raunchy film after he said it was his "dream".

A letter to John from the company's founder Steven Hirsh read: "We believe your incredible talent and passion, which have touched so many, can translate into a highly erotic adult film. Your understanding of the dynamics of relationships would undoubtedly appeal to both men and women.

"I think that together we can create a highly unique breakthrough film that will appeal to your millions of fans.

"Please call me at your convenience so we can discuss our working together. We're all enthusiastic about hearing about your vision."

John - who has previously dated Jessica Simpson, Jennifer Aniston and Cameron Diaz - said in a recent interview with Playboy magazine how his biggest dream is to write pornography.

In the article, John also admitted he will always love Jennifer, described sleeping with Jessica as like "a drug" and used the word "n****r", which he later apologised for.
