Update on the Jessica Simpson/John Mayer split rumor... It's true! "They have broken up," a source told People mag. "But they have broken up and gotten back together at least ten times before." The pair are still in constant contact, however, emailing and talking to each other many times a day. "They talk to each other at least six times a day," says the source. "I don't know if this breakup is permanent, but for right now they are broken up." As for the reason for the split, a source close to Mayer says, "John did say that he broke up [with Jessica]. He said that it was because he was just over it... He's fine about it, he's not upset - but he's definitely not looking for someone right now." Reps for both stars have declined to comment.
