John Mayer has left the Twitter building!

The singer, who had 3.1 million fans at the time he suspended his account, has left the micro-blogging site that allowed him to flirt with underage starlets and talk a little too much about his penis, according to his rep.

"With the Battle Studies Tour now at a close and a return to the studio planned, John has discontinued his Twitter account. However, he continues to communicate with his fans via his blog as he always has," his rep said in a statement.

So what was the last Mayer tweet?

"What does this button do?"
