John Mayer is losing friends — on the Internet at least.

A spokeswoman for the pop singer says he has discontinued his Twitter account with his Battle Studies Tour "now at a close and a return to the studio planned."

Mayer had more than 3.7 million followers on the social networking website. He used the account to invite University of South Carolina fans to see a free show in February before the start of the tour to promote his album "Battle Studies."

An e-mailed statement says Mayer continues to communicate with fans through his blog.

Mayer's hits include "Your Body is a Wonderland" and "Waiting on the World to Change."
