Jessica Simpson and John Mayer Break Up

"They have broken up," says the source. "But they have broken up and gotten back together at least ten times before."

According to the source, the pair are in constant contact - even as Simpson promotes her new film Major Movie Star at the Cannes Film Festival in France. "They talk to each other at least six times a day. I don't know if this breakup is permanent, but for right now they are broken up."

Another source who knows the couple confirms to PEOPLE that pair have split. "She's kind and sweet and he's a terrific guy, but it's safe to say it has run its course."

Reps for Simpson, 26, and Mayer, 29, refused to comment on their clients' personal lives.

 The day after getting Jessica Simpson's Fathers approval, The Two are Split up…. Sort of. Reports sat that they are in touch SIX TIMES A DAY???… Yeah, way to make it a clean break.

I'm Out
