Jessica Simpson and John Mayer Kaput?

Just may be, at least for now. Apparently, a source close to the couple has said that they have broken up and gotten back together many times during the course of their relationship. For now, a source close to Jessica has told People magazine that the dynamic duo has ended their romantic pairing.

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

From People magazine,

"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."

During his concert tour and her various engagements, the two have seemed rather inseparable this year and just recently, Jessica's dad said about Mayer "If Jessica is in love, I love the things she is in love with." And he added: "I want her to be happy."
