John Mayer thinks his Twitter account is a substitute relationship. John Mayer - who was rumored to have been dumped by Hollywood star Jennifer Aniston because of his obsession with Twitter - admits interacting with other users of the popular micro blogging site can be as satisfying as going on a date. Explaining his new song entitled 'Half of My Heart', he said: "It's about questions of, do I want to share my desires with someone else or do I just want to sate them myself with my laptop and my Twitter account? — these are substituting relationships." John Mayer is a Twitter addict, obviously!

The singer also shared more Tweet thoughts, John Mayer added: "Knowing that I could blog right now from my iPhone and it's up on the internet with people reading it and responding to it. How much is that a synthetic version of having dinner with somebody? How intimidating must it be to try to find an 'in' with the man who is consistently satisfying himself by all means necessary? Where is her place in that?" Photo: Fame Pictures
