Singer-songwriter -- and frequent Twitter user -- John Mayer has decided to quit Twitter, the Associated Press reports. The musician had more than 3.7 million followers when he signed off for the last time.

The departure comes three days after Mayer tweeted, "Self Portrait of The Artist Three Days Before His Metaphoric Retirement," along with a black and white photo of himself.

When asked for comment, his spokeswoman said he had discontinued his account with the micro-blogging service because his Battle Studies Tour is "now at a close and a return to the studio planned." Mayer plans to stay in contact with his fans through his blog.
